URGENT NEED FOR CLARITY & SANITY

Hello Peter. I never renewed any MTN-contract for years and visited agencies to stop unwanted renewals, many phone calls in vain. I used pay-as-you-go but still MTN pilfered my account with unwanted contracts & specials like music & odds. Never used. Had to change my 40-year old bank account at great inconvenience to stop MTN from changing code-details to withdraw monies, MTN then retaliated swallowing my airtime paid for, blocked all services and apparently black-listed me. I am beyond reason. Please help. I need to be connected by another service provider and to get back all money taken without any permission. Kind regards, Jan Wolmarans.
