Non existent after sales service

We bought a full leather lounge suite in June 2015 and paid R38 000,00 for it. Once delivered we phoned and requested that they send somebody to come and check it as the middle sector of the 3 seater couch is unstable between the two recliners. Nobody responded to my calls. In October 2015 I went to the branch only to be told that the sales person, Otis was transferred to another branch. I said that I bought from Rochester Parkview and the need to attend to the problem. I went back to the branch...the second visit where I specially drove to the shopping mall to go and see them. The man, think his name is Phillip told me that he was busy with a client and will phone me back but had the same story that Otis was transferred. I then left. About 45 minutes later I got a call from Otis and said I have to go once again back to the branch which I refused to do as I have been there twice as well as a number of phone calls. I contacted the Head Office via website, lodged a complaint with no answer. I waited another 2 days, then phoned the call centre and left a message. Nobody attended up to today to my complaint. Shocking to say the least!
