HISENSE VIOLATING CONSUMER RIGHTS

On Saturday, 17th of August 2019, we decided to purchase a Hisense Smart ULED 65” TV from Makro. The Hisense sales consultant JP made promises, high and low of how good the TV is, telling us about all the apps it has preloaded onto the TV. The one app we were particularly wary on was the ShowMax app. Got home, started setting up this monster of a TV. Started signing in on Netflix, YouTube and finally ShowMax. ShowMax logs in, shows everything, but then as soon as you try to play something, it just keeps on loading and loading and loading. Later on it gives you an error message. All the other apps is working, but not this one. I tried everything. Reset, Reboot, Logged In again, checked for software updates, but to NO AVAIL. Same error, same problem. So I decided to contact Hisense South Africa, as the TV is brand spanking new, and well within the warranty. EVENTUALLY after sooooo much struggling I got someone from Hisense to assist me. Filled in all the documents needed to log a call for someone to fix this at the beginning of September already. TO THIS DATE, 15th OCTOBER 2019, NOBODY has even TRIED contacting us. I keep emailing this person from Hisense called ‘Lushay’ but I keep getting responses like “I’ve escalated the matter” “I’ll get back to you as soon as I receive feedback”. These replies I got on the 30th of September!! I’m still sitting with a TV that’s not functioning properly!! I’ve tried everything! In the mean while, the YouTube app also stopped working. All that is working now is the Netflix app. Can ANYBODY please please give me the name and number of a place where I can lay a formal complaint against Hisense, because they are currently violating the consumer rights. They’re not keeping there side of the Warranty.
