Terrible product and customer service

hi, I have never been so disappointed at HiSense as a product and their customer service. 1st I smsed the number on the remote and was speaking to VERONICA RAMUTSINDELA via email. My Netflix was no longer working. (realized later that I need to log out and log back in everytime I want to watch it. Last weekend, nothing played on the TV, no Apps , even the hard drive was not playing. I asked the above agent what the process is, now that I have submitted all their docs, its been two days, her only response was that a technician will contact me. The screen flickers to a darker picture to a lighter screen daily. one day all the Apps play, no issues, next day nothing plays. I called the call centre spoke to a lady, who told me that I cnt return my TV for a refund since my issue is minor, she was supposed to call me after 4 to see if I need a system upgrade, nothing till now. very shocking service. and since I am not sure if I will have a tv anytime I am home, I must just deal, since my issue is not that bad. This tv was bought in May 23 2019, but I have had problems since day one. clearly wasted my money. should have just saved more money for a better brand.
