bad bed purchased

i have an account with homechoice for a while now and have ordered a few items that i have been happy with.

about 3 months back i took a restonic double bed 2 months later the bed has totally given in . For the past month i have been calling Homechoice about the complaint and i keep on getting the same response that it has been escalated to restonic and they will make contact with me .Today i called them again and received the same message . I have an very uncomfortable bed and am paying for the items purchased on time yet no one is bothered to make contact with me to resolve the issue . I have asked on numerous occasions for them to contact me again to no avial . I am utterly disappointed and have a new born baby that spends time with me on this new bed that gets worse by the day.
