The last 8 plates are greased MDF ordered, 7 pieces are delivered incl. Mdf cover plate, after a bubble they have solved it with 3 sighs. Now I thought I would give them another chance so I ordered 1 plate of wood this week. As crooked as possible. And the driver blames the on-site staff and the office blames the driver.
