Poor Service from Hisense

I bought a 65” TV in 2020. The firmware is up to date, but no access to DSTV_Now App as it always gives an error message. My Vox Fibre line is 100% at 50mbps. My other Sonny TV is streaming perfectly. Their service Department is not helping at all and has no remedy to my concerns.

I am disappointed with the Brand and the service I am receiving from their Service desk
