Disappointing Customer service at Makro (Cape Gate)

I took in my TV on the 31st of December 2018. I understand that their service providers only opened around the 7th. They established that the CPU power module was faulty. My problem is the lack of communication and customer service they (Makro) pride themselves on. In all this time I received 1 phonecall with above update. Then nothing, made numerous calls at my expense with promises to call me back and then nothing. Nobody seems to follow up and to me it seems that there is a buddy system going on where the service provider has no obligation and or deadlines, everything goes at their place and nobody is accountable. The customer (I), must suffer in the meantime while being kept in the dark. This is the worst service I have ever gotten! Communication, communication! Very disappointed!
