Terrible customer service and policies

My husband and I decided to buy game vouchers so that we could save up for a TV and not spend the money. We finally bought our tv and paid the additional 5000 cash. The tv was faulty so we took it back and tested all at store finding out that it was the manufacturer.we then decided to buy a more expensive one but there was no stock. Dion wored were the only ones who had stock left but they weren't sure if they would take the vouchers from our return. When we spoke to management she was totally uninterested in our problem and told us to take it up with headoffice. When I told her that her service and attitude was not nice she then told me that by calling the other stores game included was an extra service that she did not have to do. I don't und?rstand as she works for game and the sale would go to them regardless. Our debit order was also taken twice from the account and they insist it was or even though we have a statement to prove it and apparently it does not show. As soon as you spend money there is no problem at all but try and sort out something and it's a mission filled with attitude. It's absolutely disgusting. I could not help that there were no tv's but the staff were so
