Damaged Goods

I bought a restonic ambassador dream top masterguard on the 30.08.2012.. Because we were renovating I couldn't open the goods and see if its in the right condition.. A month after I've bought the goods I opened it only to find out that the bed is not in a good condition, I've report the matter to lewis since november 2012 and nothing has been done about my complaign ever since then.. So I've been paying the bed every month that is not in a good condition , I've also went to the shop a number of times complaigning but nothing has been done nor have they tried anything to help me
