Credit- Dispute Resolution

I logged a dispute with XDS, Transunion and Kudough on the 30 October 2019 with regards to a Temp loan from FNB that was showing on my credit record as open whilst its paid up, and only on Monday 18 November 2019 i got a email from XDS From a Lady called Jennifer Padiachy( Dispute Resolution Supervisor) stating that my dispute will only be resolved with 30days from the 18th November, which only by that date only i received a dispute resolution form to fill, and submitted all necessary required documentation including the paid up letter from FNB. The lady advised that i should instruct FNB to send the letter directly to the Bureaus.

I fail to understand why should i now be the one to instruct FNB to action the dispute while they are companies that listed the open loan on my profile, I should not be doing their job for them as its easy for them to list every activity that happens on people credit records but yet they fail to resolve disputes accordingly.

I have sent countless emails to all these services providers requesting for feedabck and have not heard anything from them. I also stated i refuse to wait another 30 days as i logged a dispute on the 30 October 2019 already and it should be resolved by the 30 November 2019

May i request assistance with dispute as its affecting the approval of credit application
