Harassment, and no response

<p>Early last year I got a new cell no from MTN . I am receiving daily calls or pre-recorded messages from Finchoice for the previous owner of this cell no demanding payment that is overdue. </p> <p>I am now receiving messages on my personal cell number giving the same messages. I have never been a customer of Finchoice, and I have never met the previous owner of the cell number. </p> <p>Further, Finchoice has clearly obtained my cell number from MTN as there is no other connection between these cell numbers. This I believe to be *******. I have contacted Finchoice by phone on numerous occasions, but the harassment continues. How do you stop them?.</p>
