Vodacom bad service

I have settled my Vodacom account through VVM Collections in September 2018 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 because Vodacom never updated my details on the Credit Bureau since September 2018 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.
