Game store in Eloff street Johannesburg

On the 4th week of March 2019 i went to Game store in Johannesburg Eloff street to return my Telefunken 55 inch tv because it was not switching on. When i got there i was told that because my receipt is faded they might reject the request to fix it so i was told they are going to request for a receipt in Head Office so that they can book it for repairs. The lady working there told me it will take 21 working days to repair the tv. I gave Game store atleast 31 working days, last week on the 30 April 2019 i called the store and i was told the tv is still with people who are fixing it. Today on the 08May 2019 i went to the store around 9am to check what is really going on, they tell me that the tv is still in the store not booked yet and because i don’t remember who helped me, nobody wants to take responsibility and i have to wait again. Someone please help me for Game to give me my tv back or a new one because I can’t any longer
