Wardrobe not assembled

I bought an unassembled Cuba 6 door wardrobe; the guys came to deliver it at 19:30pm in the evening. It was supposed to be assembled for free, instead they left the boards without assembling them and said its late. When asked when they will come back, they said they don't know and left. We are seating with a wardrobe fully paid but not assembled, very disappointed with their service!!!
