Hisense is not worth it

I bought a TV with 5 years warranty from these guys, i called them to have a look at it through Hi-Fi corporation. its been 6 working days with not a single response. Now i called in and one attendant says i must find out from their tv guy. All this time i was under the impression i bought from hisense and they owe me explanations on things i aready paid for................................I now recommend Samsung, these other brands are a joke
