Harassed by MDB

I had a Homechoice account *****ulently opened in my name. This account got handed over to MBD. I have sent through Affidavid, and documentation required by MBD to prove this is account is not mine. I even have confirmation from Transunion stating this. It has been over 2 years now and till this day I get calls from MBD, DAILY regarding this account. I get sms'd, daily regarding this account. Sometimes I can get 5 calls a day. It is harassment if you ask me. It is so frustrating because I communicate the same thing over and over and I do not understand why my details are still reflecting and why I still get these calls when I have sent all the requested documentation over 2 years ago now. Can someone please look at this.
