Hisense warranty service Pathetic.

I bought a Hisense 43" Smart 4K TV from takealot less than a year ago. The TV started showing random lines vertically across the screen on random occasions. After quite a while it started getting to the point where I cannot use it anymore as I use the TV as a computer monitor. Found out that even though it has a 48 Month warranty I could not return it via takealot and had to contact hisense directly for the warranty. I did so by reporting it on their website. No response. looked up their email and sent them a long email with photos, screenshots, invoices, serial and model numbers etc. Everything they could have needed on the 8th of April 2025. I was then contacted back and they sent a technician to come and test the TV. He arrived on the 24th of April and found the TV faulty, wrote his report and left leaving the TV with me. It is now more than a Month later and no replacement TV or refund was made. So I have now waited more than 2 months for hisense to the replace or refund. Had to buy another screen in the meantime as I cannot keep waiting for them to replace the TV. The TV was running on a online UPS the entire time I owned it so no blaming loadshedding. Even though the TV clearly states it is "LOADSHEDDING PROOF". Very pathetic service from hisense. The people from Hisense I have contacted are: Sandisiwe Mtshizana (Service Operations); Lee-anne Paul(Senior Representative) ; Phumzile Makhonjwa (Service Department) ;
