Account settled but ITC not updated even after 4-months

In July I received a call from Itcba saying that my account has been handed over to them and that a payment needs to be made. I then opted to settle the account in full and while the agent was on the phone I emailed the POP to both Mobicred and Itcba as they said Mobicred will send the closed letter. Fast forward to a few weeks ago I finally received the closed letter from Mobicred after numerous emails, WhatsApp and phone calls with no follow-up from Mobicred but as yet my credit profile has not been updated and this is still reflected on ITC. Can you urgently update this on ITC and let me know once this has been done?
