Bad service, refund back.

Bought Hisense 58 tv on the 5th of April and the sales people showed us that the tv is working fine, upon getting the tv home we noticed the upper screen has ink and we immediately informed them and took the tv back the next day on the 6th and Desmond had already assumed that we were at fault and told us how the branch manager from Vosloorus game store would jot accept it, when the manager came she actually assisted us and told us that no one is an expert and Desmond must call the Hisense technician to come and assess what happened, 5 days later the Hisense technician came on the 12th and told me that this was an internal tv screen damage which was caused by the people inside the store that were showing us that the tv was working, he suspected that when they were packing the tv back inside the building box, they handled it rough and pushed it down the box which led to the ink on top of the screen. Hisense is telling us today that they do not cover for the tv screen warranty and the lady said she will escalate to their customer care team to also investigate. Game is refusing to take the tv and give us a brand new tv since this wasn’t used ever since. I need a new tv asap.
