Pathetically Poor service

I pay my bill every month but they always sending me the incorrect bill stating that I owe more and more. When I go in to the Telkom store they always tell me that they can see that I'm paying and up to date but don't know why the billing department gets it wrong all the time. They have now suspended my service and I'm unable to use my phone to call or for data. I was given a reference number ***5 but still haven't been contacted by them. It's sad that there's not a single cellphone network in this country that can be re**** on. I will be canceling this 3 contracts that I have with them as soon as it expires. This is so pathetic.
