Appaling after sales service Hisense Smart tv

I bought a Hisense smart tv from Makro Montague Gardens just less than a year ago and picked up an issue with nothing responding on TV with it going into apps on it's own and remote not responding. I first reached out via email to hisense service department which got no response, then the day after tried several customer service numbers as the ones on the warranty card did not work, eventually got to speak to an agent who said that they will send me an email for me to respond with proof of purchase details as well as required make and model as well as serial number details in which I responded and sent all the info needed, 2days went by and got no response and decided to call them again, only to be told that they only checking email with attachments whilst I was on call, then was told that they will assign a technician who will contact me. I waited for 3days and got no call/email or sms and called once again, only to be told by another agent that would escalate to their networks team to find out what's happening. I called in today the 21/05/2024 and spoke to an agent who said that the technician assigned will call me to let me know what time in the day he will come around, I waited the entire day and got no call. Hisense has the worst after sales service and uses outsourced providers for everything from the customer service support which is a BPO based in Gauteng to their technicians who are not in house but other private repair centre's who have no care in the world about the customer and at least having the courtesy of notifying customers when to expect them. Hisense might be a brand locally made but the price of their products are definitely not worth it as once problems start and even though under warranty seems like it's just a waste of time as they just don't care about their customers.
