POOR SERVICE

I'm tired of this company called Multichoice DSTV who keeps on taking advantage of elderly people. I've been calling them every month for same thing and it doesn't look like they are prepared to help. Last month you promised that this is not going to happen again. You keep on disconnecting my mother's dstv. Someone from your side decided to upgrade her without her knowledge. You changed it back to what she had and promised to clear the balance of R70 but you did not. My sister had to pay more this month because of the R70 but you still disconnected my mother's dstv. WHY DO YOU KEEP ON DOING THIS? I HAVE BETTER THINGS TO DO THAN CALLING YOU EVERY MONTH

CAN SOMEONE SORT THIS ONCE AND FOR ALL
