Bad service, poor communication

Bad poorly service I have been trying to get my money back that they deducted from my account early February 2022. My contributions are being paid by my employer. I only pay my grandchild contribution via debit order every month. This month they deducted triple the amount, when I phone them they said that I was in arrears by over R3000. I then told them how could this be because my contributions are being deducted on salary every month. They then said they are going to pay my money as soon as they receive the rejection file from the bank. That was suppose to be last week. I am still waiting on my money. They don't get back to you, I have to phone them every time what is the status of my query. This is my last year with them, I never had any problems with my medical aids before them.
