FNB and Nimble refund

Kindly note that from the 27th of July 2024 I paid my FNB account on a settlement discount for R8,487.45.

And I mad a second payment on the 29th of July 20204 for R8,487.45, I contacted Nimble collect for a refund and I have been sent from piler to post. Nimble says FNB have them money and FNB says Nimble has the money till today I have not received my refund. Nimble referred me to an FNB branch, I went to the FNB branch and no one could assist me, however Andile escalated to *** and he again escalated to *** and then again to internal collections *** and even with this escalation the refund has not yet been paid and again I went to the branch today on the 1st of November 2024 only when he contact the refunds department I was told that even with the settlement discount I received I was still liable to pay an amount of R2000 so from the extra R8,487.45 I was not going to receive the full amount because the have deducted the R2000 and it in their GL accounts, at no point did FNB nor Nimble advise of this additional R2000. As both parties advise that I will receive a full amount of R8,487.45.

After all this time of me communicating with FNB and Nimble did anyone advise that the is an outstanding amount of R2000 only today when went to the carlswald fnb branch did the lady say that they took the R2000 and it in their GL account. So if I didn't go to the branch I was going to get a call saying that I still owe FNB even after I had settled the account.
