Payment not reflecting!!!

I received a link that directed me to your website to pay my account, and I made the payment. However, despite providing proof of payment to the WhatsApp number #*** as advised by one of your collection agents, my account is still showing as in arrears. I received a response thanking me for the payment, but the discrepancy persists. Could you please provide clarification on the status of my payment and an estimate of how long it will take for the payment to reflect accurately on my account?
