Broken sleeper couch legs

I bought a sleeper couch at HomeChoice last year around August/September 2014. In December while sitting on the sleeper couch the legs got broken. I then contacted HomeChoice on the 29/30 December. I was told they will come in 2 weeks time and 2 weeks passed by and nothing. I called countless times but only to be told the same thing \my claim is being process and they have tried calling me"but not once did i ever receive ANY CALL FROM THEM. I have always paid my account on time and never missed a payment. Came February and i am still with a broken couch. How am i expected to continue making payments when i am treated bad as a customer. Today around 14:30-15:00 (16/02) i received a call from Honechoice asking about payment"
