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.
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 ?

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.
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..
Terrible customer service. Ordered a heat pump (€5000) ten days ago, was told it would be delivered on the 3rd or 4th of July. I was told I would get another email once it was dispatched. Still no email on the 2nd of July so I emailed asking what was going on. I was told it wasn't dispatched as the were waiting for a part (wired controller). They asked if I wanted the rest of the heat pump delivered. I replied saying yes and asked when it would be delivered and when they were expecting the controller to be in stock. Didn't get an answer to either question, heat pump still hasn't been dispatched and I'm getting to reply to emails. No contact phone number. Terrible customer service. Stay well clear of this company
Defekt cirkulation pumpe som grundfos gerne vil bytte men groupsumi vil hjælp med returnering.
No passado dia 18/06/2025, quarta-feira, recebi uma chamada telefónica de uma colaboradora da shenker com a informação que tinha uma encomenda para mim. O objetivo do contato foi combinar uma data de entrega. Visto que o dia seguinte, quinta-feira, era feriado, ficou então agendada para sexta-feira dia 20/06/2025 com a condição de me ligarem 1h antes da entrega! Pois nada disto aconteceu, na sexta-feira mais ao fim do dia, dada a ausência da entrega, tentei entrar em contato com a shenker, facto que me tomou aproximadamente 1h para ser atendido após várias tentativas. Consegui ser atendido e recebi a informação que a minha encomenda não tinha saido com a justificação " o camião estava cheio "....Deixei clara a minha insatisfação e foi-me apresentada nova data de entrega, desta feita dia 23/06/2025, segunda-feira. Ora no dia 23/06, tentando perceber se tudo estava conforme combinado, voltei a tentar entrar em contato com a shenker, novamente passado +/- 40m e várias tentativas fui atendido. Fui informado que a encomenda voltou a não sair com a justificação " o camião estava cheio "......estava explicito o enorme mau profissionalismo desta.....depois de uma conversa com o colaborador, sem conseguir esconder o meu descontentamento, ficou novamente marcado para dia 24/06/2025. No dia de hoje, novamente depois de uma espera +/- 45m para ser atendido, voltaram a informar que a encomenda não tinha saido........ficaram de me retribuir a chamada e nada até então........ Friso que este serviço de entrega me custou 47,37+IVA, de um produto com 70kg que pelos vistos é demasiado grande para a capacidade dos transportes que a empresa possui Não aconselho este serviço por natural falta de compromisso, assiduidade, informação, resumindo, falta de profissionalismo! Note que continuo sem o produto que comprei e sem apoio nenhum.....
Betstellt am 03.06.25 bis dato noch nichts angekommen angegebene Lieferzeit war zwischen 07.06.25- 11.06.25 aktive Meldung über Verspätung gleich null. Am Anfang wurden Emails beantwortet jetzt nicht mehr... Stand jetzt bin ich sehr enttäuscht. Warte noch ab ansonsten trete ich vom Kauf zurück
Mauvaise expérience – à fuir ! J’ai commandé un chauffe-eau sur ce site et à l’arrivée, il était cassé. Le pire, c’est qu’il a fallu organiser le retour nous-mêmes, car le site de livreure n'a pas voulu rentrer en relation avec nous. Aucune coordination. Cela fait plus de trois semaines que nous attendons un nouvel envoi, et toujours aucune nouvelle, aucune réponse du service client. C’est inadmissible pour un achat aussi important. Service catastrophique , aucun professionnalisme. Je déconseille fortement ce site.
Ik wacht al 15 dagen op een elektriciteitskast. Ik had al 2x laten weten via E-mail dat de bestelling mocht geannuleerd worden. Toch wordt het enkele dagen later nog opgestuurd met levering over nog een week. Een Belgische website naar een adres in België, maar toch wordt dit vanuit Spanje verstuurd. 57 Euro excl btw verzendkosten en toch heel lang onderweg.
J'ai commandé deux groupes de climatisation gainable. Leur site annonçait un délai de livraison de trois semaines. Cependant, trois mois plus tard, je n'ai toujours rien reçu. L'avancement de la construction de ma maison est entièrement bloqué. Je vous conseille fortement, si vous construisez une maison, de ne pas commander sur ce site. N'ayant reçu aucune réponse de leurs part je vais saisir la DGCCRF et Europe Consommateurs.
Délai de livraison sur le site erroné et non corrigé. Suite à mes demandes de remboursement sur des produits non livrés, le service après-vente ne répond plus... A fuir.
Chauffe eau commandé (et payé!) le 31 mars en se mettant d'accord pour une date de livraison le 7 juillet (confirmation écrite de la part de Groupsumi). Le 14mai je reçois un mail disant que le chauffe eau est expédié, avec un lien de suivi annonçant une livraison pour le 21 mai. Joint par mail, le service client me répond qu'il ont dû faire "une erreur de préparation". Le 16 mai je reçois un mail disant que le colis m'a été remis ! Je n'étais pas chez moi, et aucun livreur n'a appelé ou déposé d'avis de passage. Le service client a dit qu'il allait enquêter, puis m'a fourni une photo de bordereau à mon nom, signé par quelqu'un qui n'est pas moi! Depuis que je leur ai signalé ce fait, plus de nouvelles... maj : 10/06 : Le service client refuse toujours de m'appeler malgré mes nombreuses demandes, et ne répond plus à mes mails. J'ai plus de 1000 euros dans la nature et aucun service de leur côté.
