VODACOM INCOMPETANCE DUE TO BILLING AMOUNT OF R80 000

I'm so furious while writing this. I have never done this before and are usually a very calm person and open minded. I had a contract with Vodacom for a few years and about 2 years ago due to personal reasons I could not pay the contract anymore needless to say I was handed over to a third party legal company. I made contact with them last year September for arrangements to settle the account which I pay monthly. Now I have spoken at 9:20 with a lady called Nomsa and explained my dilemma, she then put me through to Accounts I spoke with a Lebogang my outstanding account was more or less R7000 and when handed over it total to R30 000. Which is now down to R25 747.78. THE PROBLEM IS VODACOM BLACKLISTED ME FOR R80 000.00 which obviously affects my whole life on credit reviews because no payments reflect and the incorrect amount is entered. According to Vodacom only when I have settled the account with the third party legal company then they can update everything which can take another 3 years this is absurd ridiculous and against my rights as a South-African citizen. Vodacom just pull up their shoulders and say it is what it is, the worst of all is this is a multi billion company who doesn't even have a complaints department cause they probably know that all there profits will spent on that department I feel so over Vodacom I want to vomit !!!
