Lewis stores' poor services

I purchased a new lounge suite during July 2014 from Lewis stores in Ceres. I paid R18150-00 cash for it only to find out 2 weeks thereafter that one recliner was faulty. I reported it to Madelein (stock clerk) and Lewis' customer services. I was offered the Troy suite for R5000-00 more,seeing that the faulty suite was discontinued. That suite was also not brand new,but a suite from the floor that was on show. I paid the R5000-00 cash on 2014-09-03. The Troy suite was shown to me,by Madelein, on the advert LCD in store. She told me it was a brand new suite still in plastic wrapping in a store room in Caledon. When the suite was delivered,it was not in wrapping,but looked new. Adverts in store also showed it had leather uppers. Two after purchase,during November 2014, the 'leather' peeled off on the suite. I reported it the first day in December 2014 to Madelein, then two weeks after that to the manager. I then called customer services again. I only got response on 2015-01-28. The suite,which I paid R23150-00 for, was collected and send for repairs in Cape Town. I made it clear to area manager,ms. Venter, that I want full refund. Twice dissapointed by poor quality products.
