sick and tired of this medical scheme

a few weeks ago i contacted the medical scheme regarding the debit orders being taken from my account and the funds not being available so all im incurring is charges each month from my bank . i had no response until i called the credit controller whos name is Thabang , who then told me i cannot get an arrangement for my payments but he will speak to his manager and see what he can do , despite the email i received on the 06 March 2020 which stated "The outstanding contribution currently is R7,706.00 (R3,853.00 for January 2020 & R3,853.00 for February 2020). There will be a premium (R3,853.00) debited on the 01/04/2020 for March as well. You are welcome to email your credit controller on email address *** for a payment arrangement." on the last hello peter complaint it says someone was in contact with me ,which is a lie because since i spoke to thabang when he said i cannot get an arrangement to pay ,nobody has been in contact with me ,only for me to receive my statement again this morning ,meaning that by month end fedhealth will just try and debit my account again for whatever i am owing when i clearly told Thabang there is no funds in that account and i cannot close the account until fedhealth can confirm they will stop debiting , i have a new account and i am more than willing to give them that details but you guys just wont come to an agreement with me so i am sick and tired of going through this nonsense everytime .
