Hisense not honouring their warranties

I purchased a Hisense TV 3 years ago and registered for the extended warranty. they notified me that they would come back to me but still nothing There has appeared a gost on the screen and i tried to get it repaired by taking it back to the Pick and Pay Hyper by the sea where i purchaed it as i had lost my invoice. they advised me to take it to the Hisense agent in Durban but was horrible disapointed as it was in a garage and they where working on the equipment on the floor. The staff where not even interested in assisting us. we complained at the Hyper and they got the rep to contact us he was as usesless as the rest and was totaly uncoperative. From this i can only say that if you are buying a TV even although i registered it they have no record of it From this i can only say "beware of Hisense"
