Pathetic service

I am receiving terrible service from Hisense we recently bought a TV all I wanted to do was register it , at first I was having trouble I contacted customer care cant get thru , spoke to service bot that is useless emailed got a response with a link to Register which I already had eventually after several tries I managed to register my tv I responded to hisense stating that if they could send me confirmation that it is done and if my information is correct no response I waited as i know due to covid limited people and emails take long for a response however now I'm waiting too long sent an email to services, warranties as well as complaints no response I went to Facebook they told me il get a response that is all now I'm waiting like a fool and hisense cannot help me with such a simple request this is ridiculous
