Poor quality and worse service

We bought an expensive slounge set at House&Home Westgate. Two months later we could not use the one 2-seater as it started to hang on the one side and the stuffing was completely flat. My wife phoned them, left a message and got no response. About 3 weeks ago the other 2-seater started doing the same. This time my wife got hold of Kathlego who phoned her back and promised that they would pick up one set at a time and have it "fixed". This only lasted a few days and now he does not answer his phone and does not return the call when are lucky enough to get hold of somebody and leave a message. For the price we paid for this, I think the set should be replaced and not "fixed" as it looks like House&Home cannot keep to their promises.
