Vodacom bad service

I have settled my Vodacom account thru VVM Collections in November 2019 and I have a paid up letter from VVM. However, my credit check on the Credit bureau still reflects that I still owe Vodacom. I am very disappointed bacause Vodacom never updated my details on the Credit Bureau since November 2019 and this account still reflects as missed payments, dropping my credit score below average. Vodacom, sort this out with VVM Collections and update my details urgently. Vodacom service is very poor in terms of customer service, I wouldn't recommend Vodacom to any person after they have failed to do their job and failed to update my details as soon as they received their full payment.
