Harassed for account that doesn't exist.

<p> i have been receiving harrasment calls from MBD legal attorneys for more then a year now, and its still contunuing. i have called them more than 100 times telling them i do not have this account, but still i get calls day and night from them.</p> <p>this morning i got a call from a lady called Irene, she wanted me to confirm my ID no, and when i asked what its about, she refused telling, just wanted to confirm my ID to her. i refused and put the phone down, after few minutes i called MBD offices, spoke to a lady called Mmakwena, who told me the call is about my virgin active acc. when i told her that i do not have that acc, and have been harrassed by them for over a year now regarding that, she simply put me on hold. so am asking myself how do i have an acc that i dont know bout, and if ihad the acc, and the worst is, that account doesnt even show on my credit profile, which should have been. told them to take me to court regarding the acc, and stop calling me, its total harrasment.is MBD really hungry for money that much.. </p>
