Op 28 augustus bestelde en betaalde ik een raam, er werd telefonisch bevestigd dat deze binnen 15 werkdagen zou geleverd worden, meer dan een maand later, blijkt het raam nog niet in productie is gegaan, telefonische beloftes worden niet nagekomen
Na het leveren van de deur geen bevestiging haken voor de deur er bij geleverd na telefonisch contact werd mij gezegd u moet u plan trekken met u deur grote schande betaald en trek u plan nooit koop ik daar nog een raam of deur
Wij willen benadrukken dat we erg tevreden zijn over het product. Maar de service is vreselijk. Problemen achteraf worden niet meer opgepakt. Je wordt van het kastje naar de muur gestuurd. Je krijgt nooit dezelfde persoon te spreken en ze verwijzen altijd naar iemand anders en die je vervolgens niet terug mailt. Ondertussen wachten we nog steeds. En dat nadat we zoveel geld hebben uitgegeven. Nee de volgende keer gaan we naar een ander, die hebben ook goede producten, maar daar snappen ze mss wel dat je klanten behoudt en werft met goede service.
