REALLY bad service

DebtBusters stopped paying some accounts almost a year ago. I requested them to urgently change my contact details, as I lost my job, and my contact details were my previous work number and email. After numerous emails, calls and assurance that it has been changed, they still emailed and sent numerous SMS's to that contact number & email address. So my previous work saw these notices and caused BIG drama in my life.

I then called again, with my last airtime. They took 10 minutes before my called was answered. I was asked to verify myself 4 times, and got no assistance. I requested to speak to a supervisor. After holding for 5 minutes, my airtime ran out. I immediately emailed them, and had NO response - neither call back, nor email response....
