Vodacom subscriber collections

I had a 24 month contract with Vodacom from around March 2018, which I defaulted on for part of 2018 and the most part of 2019 because of personal reasons, However once I was back on my feet an able to sort out the outstanding balance I was told thee accounts has already been taken to their debt collectors VVM, I followed up with them and made a payment arrangement with them, by April 2020 I settled the account completely however VODACOM has not removed that account from my credit profile, It still shows an outstanding balance which is reflecting negatively, I have gone to the vodacom shop in brooklyn mall and menlyn mall and none of the consultants have been able to assist, the best they could do was give me a number to call and its always busy and no one even responds to my emails. The other number I called requires my vodacom number (which by now is non existent) so another dead end, I have tried everything but no luck whatsoever and I need a clean record because I cannot even get a place to stay until this is removed and this account has been settled over 6 months ago. Please get back to me ASAP
