Request for paid up letter not being honoured which is putting me at risk of remaining unemployed

I have been unemployed for year, I have an Access Facility account with Capitec that was handed over to Nimble group for collection. Recently I managed to secure a conditional offer of employment which requires me to have a clear credit check, without having an income I managed to make means to settle this Access Facility account(@ 30% discount as provided by Nimble Collection).When I request for a paid up letter Nimble group is telling me they are waiting for Capitec to provide this paid up letter while Capitec Bank can only provide me with an Incident number(#***2-I was told agent would respond shortly however I am still waiting for that agent even now). What is shocking is that when I called Capitec for the first time they were not even aware I settled my account one is taking me seriously within the CCS department or treating me like a valued customer, all they are doing is giving me timelines that they don't seem to believe the issue will be resolved by saying they will only escalating once a "certain period is passed", I keep telling them I do not have the time as my conditional offer is approaching expiry.

Right now Capitec is directly affecting my livelihood and that of my family's by standing in the way of me being employed, does Capitec know how difficult it is to get a job??? What is worse is that Nimble Collections has told me that getting a paid up letter sometimes takes longer with Capitec, why does it have to if they are a "competent bank"???The response I have received from CCS department and Nimble are enough to tell me no one is even confident my issue will be resolved including Capitec themselves so why should I believe anything they are promising at this point. Currently my Capitec Bank is still even showing the full amount as owing.

I was in a similar situation with Nedbank however they provided me with a paid up letter in 5 DAYS!!!Not only that but my credit record has also been updated.Capitec please stop playing with my life and provide me with this paid up letter TODAY!!!
