Stuffed up my credit record - no feedback

I had a contract that I soft blocked because i worked in Africa, the person who did the block at centurion never told me that they will bill me. i was given a form that I can reactivate my account when I return. I got informed via sms on a prepaid number. When following up with Centurion, they claimed that they have to get my documents from archives. After contacting them more than once and them promising me to get back to me, nothing happens. I have even emailed their collection attorneys Hammond Pole and agreed to pay the arrears just to clear my name. Not even the attorneys are getting back to me. Now I have a bad record and nobody does anything to assist. I have to pay the consumer act representatives to assist. Why must i pay if I'm willing to pay and clear my name but Vodacom or their Claims attorneys don't give a damn.
