Broken Sleeper Couch

16 February 2015 i wrote a report regarding the sleeper couch i bought at Home Choice. It got broken last year and i am still waiting for it to get fixed. Its been 3 months now. I call the Home Choice customer service 4 times in a week and about 5 times a day reporting the same thing and asking why i am being treating like this. The only time i get a call from them is regarding payment. I told them i will not be making any further payments until the sleeper couch has been fixed. My name is being put into bad credit now because i refuse to be taken for a fool. I asked them to come collect it since it cant be fixed. They told me that they will call me after 24hrs this was on 9 March but even now i haven't received a call from them. I have even spoken to the manager/team leader but still nothing has happened. At this point i do not know what to do.
