Vodacom Legal Collections: Heartless and extremely poor service

I had an account that was in arrears with Vodacom, the line was blocked and I had roughly 12 outstanding instalments on the account. I did however request a settlement from TSL Legal (which handled my arrears account on the behalf of Vodacom). The settlement was paid in full by myself and I received a confirmation of settlement from TSL Legal confirming that the account was settled in full and closed on 25 May 2023. Up to date my ITC records has not been updated and still reflects that I have 12 outstanding instalments on said Vodacom account. We have sent numerous emails to TSL Legal and even attempted to get hold of the Vodacom Legal Department which was impossible. Early November 2023 I made contact again, this time with Mr. Candrique Thumbran (TSL Legal: Vodacom Team Leader) who was extremely helpful and once again sent through a request to update all records on all associated Credit Bureaus to Vodacom. Mr. Criton Muridili from Vodacom Legal Collections confirmed via email on 27 November 2023 that my account was updated as settled and closed on ITC. This however is not the case, this morning when I looked at my updated report through my Nedbank Money App my report still reflected that my Vodacom account was in arrears with 12 instalments - same as previously and obviously not updated as confirmed. Words can not describe how disappointed I am, this just feels like an bad nightmare that doesn't want to end and is starting to affect my business and personal life drastically. Absolutely heartless and extremely poor service from a company one would not expect this sort of service from.
