Nimble Collections don't withhold money not meant for you

Good day I was paying my Capitec account to Nimble and paid an amount of R387.46 on the 30th of March 2021, not knowing that the account has been closed on Nimble Collections. I have been requesting them since April to pay the amount over to my creditor, which is Capitec bank, since I am now paying directly to Capitec bank, but they haven't and I even called them thrice earlier with no success. This is affecting my balance, as I am planning to pay off the account next year in March. Nimble Collections...pay the amount of R387.46 to your client Capitec bank since it is owed to them and not you.
