FNB don't care about complaints on Hello Peter

This review was first posted on 19 July, with no resolution!!!! What a joke

FNB provided me with a Discovery Credit card in 2015. When COVID hit, I was unemployed and couldn't pay any installments, so they handed the account to Barret and Associates, subsequently it was handed over to Brooks & Luyt. I then managed to pay off the account (last payment 12 November 2022) while handled by Brooks & Luyt. The payment has never reflected on my account and I've been earning interest on an amount I've already paid. Despite MANY communications with all parties, the problem persisted. In January 2023 the account was handed over to DMC, who are hounding me for payment, when this account is already paid up!!! FNB have been unable to help, DMC says the payment was to Brooks Luyt, so also can't help and Brooks &Luyt say they've sent the paid up letter to FNB.

How on earth do I resolve this matter, when none of the parties can assist me?!?! I am livid and so angry with the lack of help from anyone, especially since it's been 8 months since the final payment was made.
