MBD Re-Opened closed/resolved account and started calling me again

MBD consultants keeps phoning me at my work place and cell. Also keep phoning my wife and ask for me. My debt was resolved in 2010, attorney letters were send to ALL account holders which I owed and paid after putting me under administration. This account was closed, 2010 and suddenly, i started rceiving calls this year again...seems that closed accounts were re-opened which is *******! I also send numarous emails with documentation but no response...I asked to remove my number from their system, no response. 2 Minutes later, phone call again. PLEASE MBD - READ YOUR EMAILS, REMOVE MY NR & MY SPOUS' NUMBER FROM YOUR SYSTEM!!!
