Worst customer service in a while

Took my daughter's Lenovo laptop to Classique repairs at Ottery hypermarket in August of this year to have the screen replaced. I was given a quote of R1000 of which I had to pay R150 deposit and the balance on collection which was supposed to be a week later. Have been back to check on progress probably about five times in the last 3 months. I was finally contacted by a guy named Desmond yesterday only for him to tell me that the price was R1400. We then told him that we'd rather take it somewhere else. My wife fetched the laptop today and was told that he was not prepared to refund our deposit as he had only bought the business about a month ago. This, despite the fact that we had already driven over 200km trying to sort out this problem with no compensation from Classique whatsoever. I feel pretty hard done by and surely this is no way to treat clients if you are trying to start a successful business.
