Poor customer service

I bought a lounge suite about 2weeks ago at Russels Elsies river. The loungesuite was delivered 3days after we had made cash purchase. The saturday when they delivered the loungesuite we were not at home my younger son however was at home. We we came back from the malls at 1:30 I discovered that the single seaters arm rest was broken..I phone immeddiately but the store was closes.The monday morning I contacted the store I spoke with Carol she advised me that she will let the suppliers now she also told me it will take about 2 weeks for the come &fetch the chair..I wasnt happy with the idea that we bought the lounge suite cash paid R4250..and now we have to wait 2 weeks for them come and collect the chair just replace it for another one that was not broken...After 1 week I phoned again and Carol said that they will come and colkect it the next day but they didnt...After. another week I made contact with her again and she advised me to bring the chair to the store and she will exchange with another one I agreed. This morning I ask my son to take the chair to the store and ask for Carol..she is not at work today & one of her colluegues assisted my son & told him that they cant give him another chair..This made me really ****ed of with the store I phone in advised them that I will return the whole lounge suite and they give me money back cos I will go to a other store..really the service that I got from Russels Elsies river is really pathetic..I dont advise any one to buy anything from that store cos the service is ***...I want myoney back and they can collect there *** lounge suite today still???
