Can't get unlisted by Attorneys.

Account: B***. Been trying to sort this problem and get unlisted on ITC for over a year (Hamond Pole). Can't get to someone who is able to see the problem through to the end. Unpaid account. Vodacom admitted fault (I have email from Simon). I was given settlement figure (hugely different from Attorneys figure). Paid it. Emailed proof. Was told by Vodacom that Collection agency was told to close file. Now I find out it was handed to another Attorney (MBD) and now told I have to pay a huge amount again to settle. This is outrageous. Surely the Consumer Act protects me against such inefficient/tardy dealings by Attorneys?
