Couches drama from November last year

I went to buy a lounge suite in November last year and Nwabisa assisted me. It was downhill from the get go. I had to complete 3 different contracts because she made mess ups on each. Nwabisa conf my first payment will be due on the 1 March. I could not believe this so I asked her 3 or 4 times, and she confirmed MARCH !Then once that was finally done, I was told to come pay the deposit so they can deliver the couches. I did this, paying R2000.00 deposits. Only after paying the deposit, do they realise that the lounge suite I just paid for had been sold. This was the last lounge suite. They then search SA for a the lounge suite and when they finally located one, it was damaged. I asked the manager for some sort of compensation, and he refused point blank without even an apology. we arranged for the couches to be picked up end of jan for repairs. To my surprise, I get sms and phone calls demaning payment 1/02/2015, so I explain the issue and they refuse to acknowledge the major service failures caused by the company. I requested that they move my first instalment date to March but refused yet I had paid for couches that they sold, then found me damaged one. absolutely pathetic!
