Pathetic Customer Service

So I Purchased my TV in 2018 and as it is still under the 4 year warranty I reached out to Hisense to repair. After two attempts via the Website which was not attended to I called them to see how they could assist. I was then requested to send an email which I did. Guys its been three weeks, with the same shoddy response that it is still at the technical warehouse getting repaired and we will get back to you tomorrow. That's the same response I get every day. Pathetic service and pathetic call centre responses! I will definitely buy another brand in future! Just give my TV back because it does not look like you guys know what you are doing!
