Incorrect listing on ITC

Be very careful when ending a contract with Vodacom. My data contract ended last year, after the last installment was paid, i contacted Vodacom to confirm nothing was owing, and the consultant said my account was paid up and closed. I am now in the process of buying my very first house and guess what, Vodacom has put me on ITC for R13.68 they claimed i owed. I called Vodacom numerous times and a consultant in the legal department said i should just pay the R13.68 and they will completely remove my payment profile off of ITC. So at this point im willing to do anything so i paid Vodacom R20 and now they owe me money!!! I called this morning, and the consultant said they will simply update my profile to state i am now paid up. But this whole thing was not even my fault! Had i known last year when my contract ended, that there was still R13.68 outstanding, i would have paid it immediately. Now i cannot even speak to the correct person on the phone, everything is via email, and you are at their mercy whether they will admit fault and remove your bad profile from ITC.
