Waiting for refund

I took my tv in for repairs at Game Carnival Mall.It was send in to LG for a repair quotation and I was told to pay R1357.69 which I paid at the Game store. A few days after I made the payment someone from Game called me to say that LG informed them that the tv will cost R7000.00 to repair. I refused to pay the R7000.00 as the tv was not even that much when I bought it . They then sent me an sms to say that my tv was ready for collection but when I went to pick it up it was still not repaired. They gave me my tv without my refund and it has been a month now since I'm waiting for my refund. I keep on calling them and I even went in personally but it's a back and forth blaming game between Game and LG. I need my money in my account as I received bad service from the start because how can I be quoted on a repair only to be told it's going to cost more.
