useless

I purchased a Hisense TV online #*** on Wednesday the 2nd of November, was delivered on the 5th of November . Pluged in the tv and it work. Sunday Morning the tv requested a software update where after it stopped working. I send an email to customer support. Got an email and SMS that someone will contact me #***. I again sent an email on monday requesting feedback, none received. This morning 8th of november I put tv back into the box and took it to Hificorp Menlyn. there I was greeted in disgust, why did i bring the tv there??? I gave them all the info, they where realy not helpful. Tibedi the manager then called me and said the screen was cracked, I told him this was how n received it as i could see no cracks, he then wanted to give the TV back to Me with out any Support, I asked him if I can leave the TV or what should I do, he just ignored me and said I MUST take the tv. I left th TV at the shop and did not make a scene. can you please sort this out.
