Unhappy Nedbank client.

I settled my two credit cards and personal loan on 28 March 2025. I received all 3 paid up letters within 14 days. It's almost two months the gold credit card still shows outstanding and not updated on my credit profile. To top this up, I get a call from an attorney this week demanding an outstanding amount of R990 to settle my balance. I explained that I already paid and shared the paid up letter. Nedbank did you really get my payment or is this how a client gets treated. Please rectify my account and clear my my profile. I did email Nedbank 3 times with this enquiry nobody responds. No one answers the telephone calls as well. You get transferred from pillar to post until you drop the phone.
