amateurs sent to assemble my order

I placed an order at home choice about two months ago, which was a bedroom dressing table and head bored. Firstly it took forever for it to be delivered, I had to call the call Center to enquire about that then when the order finally arrives it took another 2-3 weeks for it to be assembled and even with that, I had to fight for it to happen. Now that it is assembled, we've noticed that it was assembled incorrectly, the wood was damaged and the cupboard is not opening properly. I spoke to the guys who were assembling it about what I had noticed and I was told they would come back the following day, till today I'm still waiting. I'm sitting with furniture that is incompletely/and incorrectly assembled which is very frustrating and an inconvenience. I'm sick and tired of always having to fight about the same problem whereas home choice should also do follow up on they're customers, I'm even thinking of returning the goods. Please help
