CAMAF sends debt collectors even though account is paid up

Since October 2023 I have been let go by the company I used to work for, CAMAF was the Medical Aid they used . After leaving I was under the impression that my account was upto date and and everything was in order . To my dismay I started receiving sms and calls from a debt collecting company by December 2023. When calling CAMAFD to enquire why that was the case , I was advised of an outstanding amount that I needed to pay . I paid the amount in January and was assured that , I would no longer receive calls from the debt collecting department .Today I called the CAMAF and was advised that although my account is paid up with them , I will have to pay the debt collecting company amounts owing to them .

Please CAMAF explain to me how on earth can I pay them whereas I paid you and never did your consultant refer me to them . Patiently awaiting on your response ....
