J'ai commandé une chaudière sur le site avec une certaine appréhension. Tous c'est très bien passé, de la commande à la livraison en moins de 5 jours. livrée à la date annoncée. Produit conforme à la commande. Il me reste à faire la mise en service. Je recommande ce site
Commande VODSAPJGA Je pense qu il faut toujours expliquer correctement les choses. Je ne suis pas un pro j ai acheté 3 chauffe eau sur votre site de marque thermor. On m a livre 3 chauffes eau de marque delta . J ai envoyé un mail a ce sujet a votre service client. Réponse hyper rapide oui mais delta c est thermor. OK mais comment le vérifier le doute subsiste. De plus les produits sont fabriqués en Égypte. Je suis européen français et en achetant ces chauffes eau je ne pensais pas qu il viendrait de si loin . Bravo l empreinte carbone. Je ne suis donc pas du tout satisfait

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.
Tout s'est très bien passé.
Muito rápido e muito simpáticos
