MBD - refuses to help me with fradulent account that has been handed over.

MTN *****ulently opened an account in my name. I have tried numerous times to rectify this. Subsequently, my 'account' was handed over to MBD. I tried to contact them, they keep cutting me off. And/or transferring me to the wrong people. No help from them - I have been ****med and they won't help me. I have proof of the *****ulent account from MTN. You must clear my record immediately.
