Poor service

I am appalled at the service I'm receiving from telkom. I have an unlimited data contract which I'm paying every month. However, payment was delayed for a few months for which I was charged. It must be noted that even after delayed payment I still paid in the same month. In the last 3 month my payment was up to date and telkom keeps on disconnecting my service even after successful debit orders. When I call their call center agents are very rude and impatient telling me that there's nothing they can do. I'm told my account is with collection and that I must wait for 7 days for the money to reflect on their system, meanwhile I am sitting without data during those days and yet I have paid. Why should I be punished for a service I paid for? I can't wait for seven days without service while telkom has my money and can't communicate between their departments to update on time. This is a very bad service. If this is how telkom treats their customers it's certainly bad for business.
