Samsung Electronics Customer service call Centre and Warranty Claims

I bought a 58" UHD TV on the 17th December 2020. In January the TV switched on and off by itself. This happens every 2 seconds. So I called the Customer Service to arrange for repair. First of all, The customer service call centre selection menu is sometimes working and sometimes not. Very poor!!! Eventually, I got hold of someone. Then they told me there is no service centre servicing my area, I'm staying 10km from Springs. The agent told me he will escalate this matter to his line manager and contact me. Till now no Feedback. Then I tried the online chat on their website. I had to send them photos of the TV. I did this last week but still no response. It is a very poor customer experience!
