Preposterous and incompetence behavior from Nimble and Edgars that needs the NCR to intervene.

My Edgars account was handed over to Nimble Collection Services late in 2019 who have had ample time to clear my status on the credit bureau as I paid the account up by April 2020. I have requested a paid up letter from them for over a year. And I only received it on the 28th of April 2021 after pestering them non-stop and being blatantly **** to by agents who say they Nimble group sends a clearance report to the ITC monthly for paid up accounts, and that the have requested for my paid up letter from their supervisors. Which was not the case because month- in and month out the status on the credit bureau had not changed. I went into an Edgars store which called Nimble and Nimble said it would take 24hours for the account to be cancelled, and that they have sent a request ti the ITC to have it cleared. After multiple attempts to get Edgars and Nimble group to clear my profile. Its over 12 months now and I am not being cleared on the ITC by Nimble Group and my credit is being affected negatively. WHY???? I am going to be filling in that form sent to me by the NCR upon request because the level of incompetence and I will be attaching that God forsaken paid up letter that took them forever to send to me - to even prove the shame and crminality of it: the paid up letter does not reflect the date whereby the account was paid up. That section is left empty by them. The regulator needs to put the Nimble Group and Edgars to book. I have reached my wits end with them.
