*****ulent contract

I have been with MTN for more than two decades but the trauma I am expiriencing now is traumatic. First, I got a *****ulent contract from them. I reported the matter, I returned the phones they delivered except for the two of them. I have been to their Alberton branch to get my number back without any success. They have billed me R3600 for a *****ulent contract and blocked my number. MTn is a serious mess. I cannot access very important iformation from my phone like OTPs from any internet banking I need to do. It is a month now trying to get my life back but I am sent from pillar to post.
