DMC Harassment

I have been harassed by this people for more than a year for a prescribed debt from 9 years ago. I have ignored them and all of a sudden in June and July they deducted R100.00 from my new bank account. I had to reverse the payments at cost to me. Now they have started e-mailing me at work and I have to wonder where they get the information from. I can lose my job over such mails. I have now contacted my attorney at Legal Wise to send them a letter. I'm going to sue them for ***** because they have no right to deduct money from my bank account without prior authorization.
