Poor customer service

I tried to buy TV at Makro 2023, but I couldn't finish my order because of technical issues. Last year, I got a call from TV Licence saying I owed them money for the TV I bought at Makro, but that didn't happen. I took the matter to Makro, and they were supposed to write me a letter stating that I hadn't purchased the TV at Makro, but as of right now, I haven't received it. I spoke with Akhona about but still I’m not getting helped
