Servicio de atención al cliente excepcional. Envios rapidos, materiales de primeras marcas y calidad.
Livraison très rapide et conforme à la commande
Experiencia ha sido muy buena. El pedido llegó más rapido imposible. En un día ya tenía mí caldera en casa. Pago fraccione sin ningun inconveniente. El pedido venido bien empaquetado,en perfecto estado. Todo funciona sin ningun fallo. Lo recomiendo a 💯. Es un servicio excelente.
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!!
Descrizione e puntualita' perfetta
llegó en fecha, rápido y servicial
N'ayant pas tout en stock, ma commande ne partait pas. Du coup, je les ai contacté, ils ont été très réactif et ils m'ont envoyé une première partie de ma commande avec tout ce qu'ils avaient déjà. Ils m'ont envoyé la suite de la commande dés qu'ils ont reçu le reste. J'enlève une étoile car ce n'était pas notifié à la commande que tout n'était pas en stock.
Compré un termostato para la caldera y por error compré el que no era me puse en contacto con ellos y me hicieron el favor de realizarme un cupón para comprar nuevamente el correcto. A todo esto ya había pasado el plazo de 30 días que ellos tienen para devoluciones. Tardo en llegar el nuevo porque no tenían stock, la atención por el chat de su web de 10. Gracias
