Makro Hi Sense TV's & Repairs Service SHOCKING!!!

Bought a 58 inch Hi Sense TV from Makro 8th April 2019. On the 31st May 2020 screen went black, Makro sent it to the repair company they use called Master Audio Visual. TV repaired and returned 2 weeks later. 3rd August 2020 the same thing happened again, screen went black. Makro's repair company, Master Audio and Visual collected 8th August 2020. I have phoned them on three occasions, they said the back light is faulty and can't tell me how long it will take but when it is ready they will let me know aswell as when they will be in my area to deliver my tv. It is now the 19th August 2020 and have been without a tv for half the month. This was an expensive purchase and you would expect the tv to last at least 5 years and not just 13 months and have it repaired twice in a matter of two months! I am absolutely disgusted and will never touch Hi Sense again!
