THE MOST DISGUSTING AND DISAPPOINTING SERVICE

So i bought my tv in September 2020 a 55inch Smart Tv 4k 2020 model and 4 months later my tv then decides that it will not allow 4k display anymore and the menu keeps running up as if someone was pressing the up button on the remote this would not stop even when i remove the batteries from the remote. Nevertheless i call in and ask where do i take the tv they said i should bring it in i then packed the tv up and took it to the Store at the Corner of Koeberg and Race course road milnerton. I arrived there and the place looked like a absolute dump tvs and boxes everywhere, the unprofessional assistant or technician what ever he is asked me whats wrong with my tv i explained to him and the first thing he does is gets in the typical denial mode about how there arent many 4k devices out there yet and only 4k he knows about is netflix and wants to give me a lesson about 4k the more i explain to him that when i bought the tv it works fine with my xbox one S 4k display up until it started having the menu issue and it did not want to display 4k picture any longer he said he will speak to a buddy of his as his buddy is a gamer and he will let me know Nevertheless they booked my tv in and said it was the main board and when i come an collect it i must bring my xbox with to prove to him the 4k doesnt work even after i showed him a bunch of pics proving that it did not want to go into 4k display.. anyway he gave me a page with information on my own to be exact non of his details not his name nothing like that and his description for repairs was "screen jumping" that was on the 1st of February 2021 today is the 8th of February 2021 and no one has called me or let me know whats happening, my wife called the call center on Friday and a lady said she will email us till now i have not received any emails or feedback.. i called today and no one answers not the repair store nor the call center it keeps saying mail box is full... This is absolutely disgusting service and i am shocked at the poor quality of the tv and not only that but the extremely bad service delivery. I will never ever ever ever advice anyone of my friends and family or even enemies to buy a Hisense tv never. It is my first and last time! STICK TO SAMSUNG PEOPLE!!
