Warehouse Negligence

I have purchased a kitchen unit at Bradlows about a year ago. I called and asked if they can repair it for me. It was collected and after a month I was called and told that due to client negligence I must pay. I told them to bring it back. After weeks and weeks what I got was a damaged drawer with parts missing that was in order when it was taken at home, and, the top part is missing. We called the shop and was told that the warehouse will deliver it. Its being almost 2 months and I am tired of calling and nothing is being done cause clearly they don't care about their customers at all.
