Unacceptable Service

We bought a Sinotec 55 inch LED Tv at Makro Cape Gate on the 14/6/2018, with a warranty of 5 years. 3 years and 2months after we bought the TV there is no more picture. After numerous calls to Makro Cape Gate and wrong information, we still have no TV. Makro says they will send out technician with in 48hours to come and see what's wrong with the TV, up to now no one has ben with us. Now we have to take the TV in so they can send it away for repairs which can take up to 21 days, unacceptable. If a TV is under warranty its not my problem to have it fix , must be replace , its a fight between Makro and Sinotec. I would recommend people not to buy Sintoec and they have double standards as well as Makro when buying from them .
