Poor Service - Default Listing Removal

I am not happy with the service. I had a default listed by Cartrack with the credit bureau on the 27th of May 2024. Then Cartrack debited the arrears amount on the 31st of May 2024. By June my account was up-do-date but I still had the default listing. I sent an email requesting this be addressed. I got a reply informing me that it had been forwarded to relevant department. I did not receive any feedback from the "relevant department". Seeing that this might take forever, I sent another email requesting that they provide me with a paid up letter so that I can initiate the process on my own. I did not even get a reply to this request. It's July now and I have not received any communication from Cartrack, but they were so active during the arrears period. Please assist with this.
