Never but a hisense tv ever ever again!

I purchased a hisense tv on 29 December 2020 from house and home pavilion. The next day I registered the warranty online for the tv. On the 13 July 2024 the tv stopped working and the screen is blank. Since it's under warranty I contacted hisense who is refusing to assist because they need the proof of purchase. I had advised I was doing home renovations and cannot locate this.also, since the tv was bought in 2020 I am sure the receipt would be faded. I contacted the store u bought the tv from for a reprint of the recipient but they advised they changed computer systems and they only have records for the last three years. Now I am left with a tv that doesn't work which is on warranty until 2020 and hisense has proof the warranty was registered but is refusing to assist because the receipt is missing. They should have asked to upload proof of purchase when registering a warranty. I have two hisense tvs. I regret purchasing this brand. Pathetic service from their warranty department.
