Incorrect billing

With regards to the initial complaint I logged REQ***. I must say I am very disappointed and irrite with my experience with MTN that I expect a feedback of my call about their billing, unlike having to be blocked without any feedback as to what the reason for my bill to have outstanding balance whereas I pay my normal instalment and NEVER went over any of my limits. The call center is just useless for me because they only read what is on my account and that is it. Again I keep on receiving electronic statement which I have stated numerous times that I want posted statement. My lines can not just be blocked without any communication and only realise that I am blocked when I try to make a call. <br> <br> Next step is cancelling my contract and port to another service provider that will view me as important. This network really sucks and legal route is not even worth it at this point
