Pathetic service from Hisense Support

Very poor service from Hisense Support - I logged call for my TV on 02 February and it has not been repaired as yet. I had to call the Service desk to ask when my TV will be attended to and that's when they allocated my call to a technician. The technician also didn't make proper arrangements with me to start with. I have called numerous times to escalate and complain with no luck. I have bought quite a number of Hisense products and did not expect to struggle like this with a tv that is still under warranty.
