Poor service and pathetic communication

My child dependants was updated as adult dependants without my knowledge and also without me submitting any docs or calls to Bonitas to do so. I noticed this change on my payslip for the month of January 2023, i then called the service centre because i saw an amount of R3236 was deducted extra for medical aid contribution. I called Bonitas on 19/01/23 and was told a query will be logged to the membership dept, i then called again everyday and was told that a refund will be submitted because the error was on Bonitas side, only to follow up again today and was told by the consultant, Karabo, that a refund cant be done only the contribution was rectified on the system. Not once did Bonitas reach out for the error they have made and the service centre staff is *********** because they told me they couldn't answer on behalf of whoever made the error. This month im suffering a loss of R3236 because of an error made by Bonitas and this can only be refunded once the funds are being received by them from my EMployer, this would not have happened if they did not update any details which was not received from me, why update details if you have not received anything from the member and to top it off, no communication at all!!!!!!!
