VERY BAD SERVICE

I bought a Hisense 65 inch TV from Game Festival Mall in June 2020 and mid May 2022 the TV just went blank not showing picture any more. I lost my receipt but had my payment details from my bank so I went to the shop got referred to 3 persons each time had to relate my story before I got to the said right person a lady who was very helpful, she asked me to write all my details in a book and that she will refer the matter to headoffice to retrieve my receipt first and then she can log a call with Hisense technician to come and fix my TV and the process to retrieve my receipt will take 3 weeks after which they will call me to book a date for the technician to come. I waited for 3 weeks no phone call I went back on a Sunday to customer service office and again had to relate my story to 3 persons only to be told that the lady that deals with my issue is not on duty I should come during the week. I went back the following Saturday and had to be referred to again 3 people then finally they called the lady that took my details and all she said was that I still have to wait. I then asked to see the manager and was referred back to this other lady that I had spoken to before and then she said I shouldn't have to wait for that long so she took my details again and spoke to someone on the phone and then she asked me to wait when she came back she said the lady that's gonna assist is currently on lunch so she asked me nicely to come back in an hour's time, which I did and was now told that they can't pick up the bar code number in the system so they have to escalate to head office and I should get some feedback by Tuesday. Today is Thursday and no feedback at all.
