My order was delivered on time no problems. Tracking was a little bit off because I received an email saying that my order was delivered but i didn't receive anything. I called the courier and left a message they called me back and explained that my order was already at the local distribution center and it will be delivered tomorrow and the next day the driver called and informed me that he was on the way to my house. The other problem is when I opened the packages the manual and the mounting kit was missing i send them 2 emails but but nobody has been able to help me with this issue. From what I understand is once you receive your order and if anything is wrong you are stuck with it. Unacceptable on there behalf..That's my last order from this company.
Muy mala experiencia con Group Sumi. Hace más de cinco meses se me averió una placa de domótica Delta Dore que todavía estaba en garantía. Contacté con ellos y estuve en comunicación con Mariona, quien me indicó que enviara el producto para su revisión. Seguí todos los pasos, lo envié, y desde entonces no he recibido ninguna respuesta. He escrito varias veces para saber qué ha pasado, pero no he obtenido ninguna solución ni explicación. Comprar online parecía más barato, pero al final sale mucho más caro cuando hay un problema y nadie responde ni se responsabiliza. Una empresa que trabaja con tecnología del hogar no puede permitirse este nivel de abandono al cliente. No recomiendo Group Sumi. A día de hoy, sigo sin el producto y sin respuesta.

Wir haben am 17.04.25 eine Bestellung (BKJLMBQTP) getätigt und auch sofort bezahlt. Bis heute haben wir die Ware nicht erhalten und erhalten trotz mehrfacher Nachfrage entweder gar keine Rückmeldung oder man beantwortet unsere Fragen nicht. Telefonisch ist eh niemand zu erreichen, auf 20 Mails bekommt man vllt. eine Antwort. Nach unserer Erfahrung ist das bisher Betrug und man sollte hier nicht bestellen. Wir werden heute Rechtsmittel einlegen, wenn man sich weiterhin nicht meldet.
I bought 2 heating pumps, 2 months ago. Still don’t got it.. I wrote to them on chat and they said they would contact the shipping company, with promise that I would hear from them the day after. Now it’s 2 weeks ago, and I’ve texting them on the chat 5 times, with no answers…
Ich weiß nicht warum es hier so viele positive Bewertungen für diesen Händler gibt. Ich kann das nicht bestätigen. Ich habe am 21.03.2025 eine Samsung Klimaanlage bestellt 1 Außeneinheit mit einem 2,5kW Innengerät und mit einem 5kW Innengerät. Diese sollte am zwischen 9 und 10 April geliefert werden. Nach diesem Datum fragte ich die Mariona vom Livechat und wo die Anlage bleibt, Sie sagte mir dass das 5kW Innengerät fehlt und noch nicht im Lager eingetroffen ist. 2 Wochen später habe ich eine Teillieferung veranlasst weil das 5kW Innengerät wohl immer noch nicht im Lager eingetroffen wurde. Am 30 April ist wohl das fehlende Gerät eingetroffen und es wird mir von Tag zu Tag versprochen dass es versendet wird. Wir haben heute den 12 Mai und das fehlende Gerät wurde immer noch nicht versendet. Auf Anfragen im Livechat keine Antwort!! Finger weg von diesem Onlinehändler!!
Bestellung 1: Bestellt wurde eine Klimaanlage mit vier Innengeräten, Kanalabdeckung und Schlauch. Geliefert wurde lediglich die Kanalabdeckung – der Rest fehlt. Trotzdem wurde die Bestellung als vollständig geliefert gekennzeichnet. Anfragen an den Support blieben bislang unbeantwortet. Keine Empfehlung! Bestellung 2: Zweite Bestellung umfasste zwei Klimaanlagen – geliefert wurde nur 1. . Auch hier erfolgte bisher keine weitere Kommunikation, obwohl die Lieferung als vollständig abgeschlossen markiert wurde. Erneut: Keine Empfehlung für diesen Händler.
No delivery for weeks, no info. For 3k EUR AC order. Feels like a scam.
In de eerste plaats kwam de geiser met dagen vertraging aan. Doordat het een onbekend merk was kon ik geen installateur vinden. De geiser kreeg ik ook niet aan de praat en een handleiding in spaans en Portugees hielp ook niet echt. Alleen via mail om hulp te vragen, met als antwoord dat ik in de handleiding moest lezen. Gratis retour zenden op basis van "niet werkend" werkte niet dus maar betaald retour gestuurd. Nu ruim twee weken geleden hebben ze het apparaat retour ontvangen, maar nog geen geld terug gezien en geen antwoord meer op mijn mail om te vragen waar mijn geld blijft. Vlak na deze review, kreeg ik een mail dat de retour betaling is voldaan.
Dit bedrijf verkoopt goederen en geeft op hun site een levertijd aan die ze niet kunnen waarmaken. Wanneer u contact opneemt krijgt u als antwoord dat ze geen levertijd kunnen zeggen omdat ze zelf niet weten wanneer ze de goederen zullen ontvangen... en raden ze aan uw bestelling te annuleren. Ondertussen zit je wel met meer dan n maand vertraging met uw werkzaamheden. Wanneer u vraagt naar een alternatief wat wel leverbaar is, krijg je geen antwoord meer. Misleiding van de kopers door aan te geven dat het product bij hun wel snel leverbaar is.
Materiale non conforme alla descrizione. Il corriere nel trasporto del reso ha danneggiato il pacco, e quindi non ho potuto neanche riceve il rimborso. Non consigliato.
Thats already 43 days that i have paid. Still not recieved any update on my purchase! Since second week they are postponing to the next week. I have rescheduled the installations already 4 times. Deliver time was 10 days according to the website when i placed my order. Its so frustrating that they show no responsibility for this issue. Lastmessages of mine are not even been responded.
Ordino una caldaia ad agosto 2024. Installata a fine gennaio 2025 in seguito ai lavori di ristrutturazione e ci rendiamo conto che la caldaia perde acqua ed è difettosa. Contatto Groupsumi e non rispondono alle mail. Dopo un' altra settimana li contatto e mi dicono di rivolgermi a Bosch che mi nega l'assistenza in Italia perchè il prodotto è fatturato in Spagna. Loro dicono che Bosch deve offrire l'assistenza e mi richiedono una lettera nella quale Bosch dichiara di non volermi assistere. Invio copia della lettere e scompaiono. Mi ritrovo quindi con un prodotto guasto, senza assistenza e con un rivenditore pessimo che da 3 settimane mi ignora non offrendomi alcun aiuto. Ora mi tocca provvedere a mie spese ad una riparazione per oltre 200€! Evitate di comprare da loro perchè non avrete assistenza sui vostri prodotti e la garanzia in Italia non vale, inoltre la loro assistenza è inesistente e dovrete piangervi tutto da soli!
Es imposible contactar con esta empresa en España. No tienen número de teléfono, el único que hay 930344099 está bloqueado. Hicimos una compra de radiadores de casi 1000 euros el 2 de diciembre y hasta hoy 3 de enero no tenemos respuesta de en dónde está el envío cuando supuestamente llegarían el 16 de diciembre. Estamos en reforma y nos tienen parada esa parte de la obra porque no llega el pedido. No podemos creer esta falta de profesionalismo, parece una estafa! La empresa de transporte con la que trabajan, DB Schenker, también es imposible de contactar. Necesitamos respuesta!!
DESASTRE DE ENVÍO, ha sido un infierno el envío y aún esta por solucionar. El transporte extravió parte de la mercancía en el primer envío, posteriormente en el segundo y tras pasar 4 días no ha llegado, ahora me dicen que tardan en repartir 3 días más... Desesperado voy a recogerlo en la agencia de transportes, espero que esté todo correcto, si no haré otra reseña en función de lo que suceda... cómo digo, un total desproposito.
Extreem lange levertijd (+10 dagen), maar 1 contactmogelijkheid (email). Geen reactie op de chat tool op hun eigen website.
Ho effettuato un'ordine di un Misuratore di energia Wallbox monofase max. 100A, arrivato in ritardo rispetto a quanto concordato, pagato 95,77€. Lo rendo indietro facendo pratica di reso e dopo ben 10 giorni che hanno ricevuto il reso mi vedo accreditare l'importo di 81,00€. Non ho capito che politica di reso adottano, non viene specificata sul loro sito. A MAI PIU'
I ordered some Tado radiator thermostats from them and there was no progress for more than 2 weeks. Products still not delivered I have requested a refund but doubt I will get it. EDIT: I got a refund, but will not recommend to use them in future
suite à achat d'un chauffe-eau tombe en panne. Sous garantie mais pas de proposition d'échange, de remboursement ou réparation dans un centre agréé ou pas. Ils essaient de faire reporter la garantie sur le fabricant. Plus de réponse depuis.
