Horrific Service - still waiting for an item that was purchased late Jan

I am a first time buyer at Rochester, Rustenburg and what a terrible experience it has been. I first went there around mid/late January to buy myself couches. I made a choice and enquired on the price and was told the couches were going for around R37 000. When I came back a couple of days later to get their banking details so that I could make a purchase, I was told the sales lady who had assisted me had made a mistake, the couches were R43 000. I then asked about their swivelling single couch and was advised that it could be adjusted to be fixed. I went home to discuss with my husband on the preferred option for the single couch (take the fixed or swivelling). When I went back to the store, this time I was told the swivelling chair cannot actually be adjusted to be fixed. I was annoyed from the ill informed staff and decided to go the Pretoria store next to Pretoria East hospital where I was given such a wonderful service, with the staff who new their product. I then paid a deposit of R18 000 and advised them that I would pay the rest of the balance the following day. I got a call later that day from the gentlemen from Pretoria who told me that the sale had been taken away from him and that I would now be assisted by the *********** staff from Rustenburg. I did not want to make an issue and accepted that. I was informed that I would receive my couches after about 8 week. When they did arrive 8 weeks later, the swivelling couch was totally skew. We called the Rustenburg store to complain and I was told to send them a picture which I did (that was on the 10th of March 2016). A week later, we had no feedback and my husband had to go to the store to complain that they needed to fetch the chair. That also took a couple of days. Eventually about two weeks and more later, the couch was fetched from our house and we were told it would take another 8 weeks for us to receive our swivel chair. It is now the 06th of May 2016 and I have not received that chair. The last communication from Rochester was about 2 weeks ago informing that they were 'busy' with the chair. And this is a part of a set that was paid R43 000 in cash around late January 2016. The chair that was to be redone was taken in March 2016. I do not think I am being unreasonable if I say that this store is a total nightmare of incompetence. A couple of months later, I am still yet to enjoy my full set of couches!!! And this coming from a new customer. Makes me wonder what they treat their regular customer like.
