CSD Verification Failure

For the last two weeks I have had excruciating difficulty with FNB around my Bank verification on the CSD portal. I have gone to the National Treasury and visited FNB themselves to no concrete solution. All I need is the bank to verify on CSD portal that I bank with them, for the bank to advise why for the last 3 times, they have declined my banking details, and the call centre agents at FNB and the Business Banking Manager in Ingrid Magwaza at Hayfields Branch, Pmb has simply advised me on how I should write my details. As it stands I have now missed 2 payment runs from the Department which I am awaiting payment from. I took the advice given by Ingrid Magwaza and updated my details accordingly yesterday, however, since this was submitted yesterday, I will only receive a response on Tuesday 19.05.2020. So, say my details are declined once again, I then miss yet another week for payment from the Department. I need someone at FNB to check my details individually and advise how/what needs to changed or if this time it will be approved. Waiting for Tuesday is not good enough as the delay will jeopardize me further. Please can this be resolved amicably
