poor client service

I took my Hisense tv back to incredible connection paarl mall about a month ago because the tv just switched off 1 day and when we turned it back on there was no image, it was just dark.i called the shop 2 times already and they cant give me answers as to when the tv will be fixed or if the tv can be fixed.i also send an inquiry on hisense's website explaining all the details but no feedback. This is unacceptable and its extremely bad and poor client service because they were quick in convincing me to buy the tv but now that there is a problem they couldnt care less .my tv is still under warranty and i cant afford to spend another month without a tv!!
