Bad service from Vodacom

I am writing this to please intervene and help clear my name. I had a cellphone contract with Vodacom and the contract came to an end 2 years ago. I decided not to renew the contract and paid up the account. However, I'm still surprised that when I check my credit score, I'm still seeing vodacom account with arrears of R2800. I communicated with vodacom several times telephonically and through their email:***, reference no. 002B4aGWHK6BH4X3 where they confirmed that my account is settled and closed and the ITC is updated. This email was sent on the 13th of January 2022 and to this date the ITC is not updated. I've also communicated with Experian and they requested for a paid up letter which Vodacom is failing to provide. I've tried to communicate with them through their call center but I'm always directed to the wrong person, the phone will automatically be hanged up. I am tired of Vodacom for not keeping their promises and I advise anyone coming accross this to never enter into a contract with Vodacom. Their customer care is not on point.
