repairs/bad attitude

Bought a plasma from Game westgate and it was faulty within a month. I took to the store for repairs, when enquiring about the status I was told that it was my fault the TV is not working because I fidgitted with the TV. When I wanted to collect my TV from the store they didnt know where it was even the store manager. The store manager said he cannot help me and that his store will refund me the TV amount minus the repairs amount. Game westgate has ****** me of R1800. I am openning a case againts the store. My house is full of game appliaces and gadgets. And i am treated like a nobody???? Never again will i or my business purchace from game
