Credit Ratings Affected

I have logged a dispute with Vodacom concerning excessive data useage and have concluded that i make monthly payment arrangements which I have done. Only to find out 6 months later that they have *****ed my credit profile and I cannot obtain finance from bank due to their listings.I have chatted endlessly to the legal team and customer care but to no avail. I feel that Vodacom has been unfair to list my name and all I want is for them to remove and update my status with credit bureau.Thanks <br> Account number provided.
