Ik heb hier een midea portasplit airco besteld deze werd netjes verzonden en ik had hem niet meer nodig. Ik heb de courier laten weten dat ze het retour mogen sturen en ik heb groupsumi laten weten dat het product retour komt en ik dus een terugbetaling wil. De airco is inmiddels al 2 weken bij de afzender maar ik heb nog steeds geen geld terug ontvangen. Erg vervelend dat het zo lang duurt
Ich habe am 23. Juni bestellt und die Ware sollte achten bis 10. Juli geliefert werden. Leider habe ich weder eine Bestellbestätigung erhalten. Noch wurde auch zwei Nachfragen per Mail bezüglich meines Lieferdatumsreagiert heißt. Ich habe gar keine Antwort bekommen der Chat funktioniert zumindest bei mir auch nicht. Soweit versuche ich, die Bestellung jetzt zu stornieren und auch gleich mein Geld wieder zu bekommen.
The prices are good but the service after purchase isn’t. Orders are a week later than planned (still hasn’t arrived) and when contacting support on a new delivery date (in order to plan installation by local company) I get no answer. Also not possible to cancel order even though it hasn’t been shipped after 16 days. Customer service says I have to wait till it’s shipped, reject the package at the door, and let them send it back. I ordered an airconditioning unit, but then decided to go for a bigger unit, so I ordered that as well. Cancelling the first order hasn’t been possible and I have more than 1000 euro’s locked up and waiting because they want to ship it first (again, still hasn’t been shipped after 16 days). They claim the reason is because they work in a logistical warehouse, which I understand, but it’s been so long it must be possible to get that package out of the process. When asking about product information before purchasing they reply very quick, which is nice.

Il manque un article dans la livraison et 2 jours aucune réponse alors que il y a écrit réponse en 24 h j’ai eu aucune réponse Colis incomplet pourquoi ?
Kaikki toimi asiallisesti ja tavara saapui hyvin pakattuna ja oli juuri mitä tilattiin. Hyvin olisi voinut antaa kaikki 5 tähteä, mutta koska lähetys tuli Espanjasta asti, siinä kesti aikansa. Mikä sinänsä oli ihan odotettua ja ok, mutta kuitenkin huomioitava arviossa jotenkin, muuten ei eroja tulisi ollenkaan jos hommat hyvin toimii. 4,5 :-)
Am 3. Juni wurde die Ware bestellt und bezahlt. Nach mehrmaligen E-Mails sollte letzte Woche Freitag die Ware ankommen. Leider sind nur die Dämpfer des Außen Gerätes angekommen ein fünf Euro Artikel. Leider bekommt man keine Rückinfo. Und auf E-Mails wird nicht geantwortet.
Comprei dois ar condicionados no dia 18 de junho. Hoje, dia 8 de julho ainda não recebi a encomenda. Não consigo contato com a Summi ou com a transportadora.
We hebben bij dit bedrijf een airco besteld. De airco is erg snel geleverd, op zondagavond besteld en op donderdagochtend was het al geleverd vanuit Spanje. Klantenservice reageert snel bij eventuele vragen. Het is ook allemaal netjes verpakt op een pallet.
Très professionnel
Bestellt, zwei Fehlartikel sofort nachgeliefert. Die Fehlartikel waren allerdings m. E. das Verschulden der Spedition (unsachgemäße Ladungssicherung, Pallette ziemlich lädiert) Insgesamt-gern wieder
Très efficace, professionnel , produit de qualité, envoi rapide, je recommande
Etwas lange Lieferzeit, alles andere war super
Por la disponibilidad del producto y fecha de entrega
Une climatisation commandée, jamais reçue. Un mois et demi de mails, avec parfois une réponse bateau. Aucune solution proposée ni remboursement. Plus de 500 euros. Pour ma part site à fuir car en cas de problème, débrouillez vous..
