Vodacom Refuses to Update my VCCB credit bureau profile.

Re: Vodacom (Pty) Ltd Account No: I***-7 This letter shall serve as proof that the above referenced account has been Paid in Full. Based on the above, we have instructed our client Vodacom (Pty) Ltd to update the default information and the payment history to reflect that the account is Paid in Full. Furthermore, please note that in order for these records to be updated, it can take a period of 21 (twenty-one) working days from date of notification..

The above is the paid up letter from Vodacom lawyers . I have for so many times advised them to send an email or answer VCCB credit bureaus that the account has been paid . No answer since June , am just wondering if my issue will ever be taken serious by Vodacom .
