WORST CUSTOMER EXPERIENCE

My Hisense TV stopped working around June, I took it to Game for repairs because the TV was still under warranty, but since I was no longer in position of proof of purchase they had to go and search for the receipt based on the date of purchase, three weeks later after complaining I was called to bring in the TV, the TV was fixed but 4 months later the TV screen just went dark. I reported the issue to Game Boulders Mall now they are telling me I have to through the same process again of waiting for 3 weeks, I pleaded with the manager because it doesn't make sense to go through the process if we still have repair No from the June repair which has every detail they need, the manager assured me that the process has been improved and it wont take more 2 days to retrieve the proof of purchase, 9 days later I'm still waiting and at this rate I'm facing festive season without TV, THIS IS THE WORST CUSTOMER EXPERIENCE 1STLY I HAVE LOST FAITH IN QUALITY OF GAME PRODUCTS AND THE REPAIR PROCESS IS A NIGHTMARE IT IS LIKE IT WAS DESIGNED TO FRUSTRATE THE CUSTOMERS TO RATHER BUY A NEW PRODUCT SADLY I WILL NEVER SET MY FOOT IN GAME STORES AGAIN.
