COLLECTIONS DEPARTMENT

About 11 April I wrote that my account is now paod with debit order since March 2023 while i was paying by EFT since 2020. My payments does not show on my account. I spoke to Manilishe, Nelsiwe and Alesia. I was told to send POP to natha********. No response. Then I was told there is Nathalie Donkerman in that department. I was then told to send POPs to ***. Still no response. Then i was told to send POPs to ***. The response was that the mailbox is full. I sent again and got same response. I sent my info again to *** I still have not received any response. What is my next step?
