Bad Service from Daniel Shabangu

Paid my credit card in full on 2022/03/30. It was a transfer from my Nedbank Cheuque account to the credit card. Sent 3 emails to Daniel Shabangu to confirm if payment is reflecting and if credit bureaus were informed. Sent another one and asked if he can acknowledge receipt and of my previous emails. No response up to so far. He is no longer working for the company or is he maybe on leave hence to response to my many emails?
