No reply from Game for TV repairs

I gave my Samsung TV for fixing on the 28th of May the person who was helping me said I will get an SMS with the contract details of where the TV is going. It's been six days now and I have received nothing from Game not even a phone call. I am very irritated because I keep calling the store and I'm put on hold for hours on end. This is not very professional for such a big store to have people waiting for something they have paid for.
