Customer Complaint - Poor Service from FNB Credit Card Legal Collections

I've been struggling to get feedback from FNB Credit Legal Collections, after I paid and settled my credit card in full. I've been sending emails to *** with no response since 09 May 2024. All I need is a settlement letter. Proof of payment was sent on 15 October 2024 and no feedback since then despite several attempts to contact FNB to acknowledge receipt of payment of an outstanding amount. Bear in mind, the balance changes daily as this is an interest-bearing account.

I qualified for 25% discount from the current balance .

Current balance R28,486.66 less 25%

Discounted balance R21,364.99

Paid R21 500

This puts me in an unfavorable situation.
