Bad Service

I a very disappointed with Vodacom, I had a contract which I have completed the payment, but they refuse to update my credit profile with ITC and credit bureau. I have called countless times for assistance but the just promise that it will be done within 7 days but nothing gets done, I have also e-mailed but I am not assisted. I have been trying since the beginning of February 2021. Im frustrated and I want my profile cleared as soon as possible.
