Lack of service and proper communication

I have been waiting on feedback from you guys about my monthly payment, you have now cut my internet mid month even though I have paid you guys. there is an outstanding on R140 which if prorated means you guys can only disconnect my service closer to the end of the month. whats worse it that, the error originated on your side due to an error made by one of your consultants quoting that my monthly contribution is R695, I have been waiting for an apology and resolution of this error and nothing has happened to date. I am at the point of cancelling this service due to lack of service and proper communication.
