Bad service and attitude and NO response after 72

I have on Monday, 09/02 16h18pm entered this store with my Sansui 50 inches for repairs, I was immediately directed to pay R350.00, thereafter to (I MADE A VIDEO OF THE INCIDENT ) customer care, where only the RUDE, ARROGANT and UNCARING Anna was the only person working to assist a queue of 7 people, I then asked her if there is no other people to assist, she knotted in arrogance, I asked for her manager, she refused to identify the manager or to give me a name, however I decided to wait and have my TV booked in as I have already paid, she then reassured me, upon booking the TV that, within 48 hours I will get a call to confirm the quotation to fix my TV which I bought from Hi-Fi Corp, March 2011, to date, after 72 hours NO call from them to confirm my quote, considering the service I got from Anna, I expected this kind of service THEREAFTER. I now what I want from Southgate H-F- Corp, is to REFUND MY R350.00 AND RETURN MY TV UNTOUCHED BY TOMORROW, 13 FEBRUARY. They have failed to honor their verbal promise, which as per CPA Act is legitimate and binding, I as well cannot be bind to their R350.00 non-refundable. DISGUSTED and DISMAYED of Southgate Hi-Fi Corp's stinking service.
