Bad service on repairs of LED TV

I bought a 65'' led uhd tv from Makro. After 3 days the screen went dead. I contacted HI SENSE and was told to return the tv to Makro for exchange. This was a serious exercise but eventually got it done. The replacement unit lasted for 2 months and the same thing happened now. reporting this fault by email JJ requested i must produce the payment receipt in order for them to attend to the matter. After several mails and calls a repair order was given to Microlight appliances services to carry out repairs. The so called technician came to inspect the tv and <br> without opening the unit made his findings it is the main board. He had no spares with him and i was told he must collect this spares from HI SENSE and would be back on Friday to repair this tv. I called the repair centre on Friday morning and was assured they will be repairing the tv at around 14h00. This did not happen. I contacted Hi Sense and spoke to JJ and he assured me he will get back to me shortly needless to say it did not happen<br> The gaurantee offered by Hi Sense seems like false promises, DO NOT BUY HI SENSE PRODUCTS if you want to save yourself a lot of headaches. Legal action will be the next step for resolvement
