Horrible service

DSTV they say one thing and do the other. I'm being charged for months which my services weren't active. When I made an arrangement with them because I was suspended for 2 months, the response I got from them was they gonna disconnect my servuntil such time I can make a payment. To my surprise when I want to make a payment, my bill is three times the amount I'm supposed to be pay. I've battling with them the entire week to fix the error but I don't seem to be winning. No kne in their staff can explain this billing error
