Hisenae TV - Waiting for repair service - going on two weeks!

I bought a Hisense TV 2018 and last weekend it just decided to stop working. Called them and they ask that I provide proof of purchase. Luckily, I still had the receipts. I emailed all the documents they requested for past week Tuesday already. Today I received an sms indicating that I CANCELLED the request have sent them numerous emails and called for feedback and all they say is the tech will attend soon. Now after they have cancelled the request, do they expect me to start the 9 day process again. Really! They must be out of their minds. How does one get service from Hisense. I am frustrated! I regretted purchasing their TV. HISENSE
