MTN ********** account

A MTN account was **********ly opened in my name. I have had money go off of my bank account. I have tried resolving this with MTN. All I want is a phonecall to resolve this. I have been in contact on Twitter but I just want someone to speak English to me. This has RUINED my credit record!! This needs to be rectified immediately!! Please can someone with some AUTHORITY give me a call. Each time it is a different amount and I different story. I have provided ALL the necessary information requested from MTN to report a ********** account and this has still not been resolved.
