Defected lounge suite

I bought a leather upper lounge suite from House and Home Gateway in Feb 2014. Within the first few months of purchase the lounge suite began to tear and come apart. I lodged the complaint with House & Home which they escalated to Calgan. The lounge suite was taken to Calgan Jhb for repairs but was returned over a month later in the same condition. They refused to repair even though it was under warranty. House & Home shifted accountability to Calgan. The seat on tge 2 seater cavdd in and broke, stitches openened up, seats are torn. I spent thousands of rands on this lounge suite which is so badly damaged due to the poor quality of material used. Calgan refuses to replace this product. I have emailed them and to date haven't had a response. It seems that Calgan is big on profit and have no interest in customer satisfaction or their integrity. I have failed in my attempts to get tge lounge suite replaced. I sincerely hope my complaint is attended to with a positive outcome.
