Poor service from Polmed **** not medscheme

Polmed deducted my money twice on my payslip on the 15 /01/2024, I then contact them to ask them, they told me that they deduct in advance so I said how do you deduct in advance, she couldn't explain further. I told her that once i was in a marine plan ànd that thing did not happen. I send that copy of my salary advice to them via email so on 22/01/2024 I received an message saying they are going to refund me through the persal. On 31/02/2024 I contacted Polmed to find out about my money that lady who was so clueless told me that she does not see or have access to check the money and I told her about the sms that I received on the 22/01/2024, she did check and she told me that she can see the sms but she will take the matter to the relevant department and they will contact me within 1 day but up until today I did not receive any call from them. On 01/02/2024 I send to two emails to them they did not reply. I feel like Polmed is useless not useful. I do have two colleagues of mine who joined last year but Polmed did not deduct twice to them which is cst Mabote and cst Mojanaga
