Poor quality and bad service

I bought machine with makro last year February brand hisense hardly a month after purchase machine was booked for repairs 8 months down the line the machine is giving me same problems, now they don't wanna exchange the machine for me, it's clear that the following product it was a factory fault, if they are persistent in fixing the machine I gave them a fair deal that they must compensated with a R1500 voucher cause clearly I've been ins huge troubles with this product which they recommended highly by their shop brand promoter, this means it's false adverti*****t which I will be taking with consumer ambudsman cause they are giving wrong info about their product.
