Rochester sells low quality corner couches

I bought a corner couch at Rochester Woodmead December 2020 on credit.around 25 June 2021 the couch started giving me problems and I called them ,they came and took the couch for repairs and returned it(by that time it was still within 6 months CPA rules).my couch was taken for repairs 3 times,that’s when I realised that no this thing will give me a problem and I will be done paying them so I will not go back for repairs.I told them I no longer want the couch I want a new couch and of quality.they are now giving me stress,they don’t want to refund or exchange the couch they are telling me about the supplier refusing to refund,they never told me about this supplier when I bought the couch.I would advise people not to buy corner couches at Rochester otherwise you will cry and waste money.I want my money back or be granted opportunity to go to store to pick up another couch of quality
