Pathetic service, no joy. Money deducted. Incorrect information given.

In 2017 we had changed over from personal payment to employer group. Personal bank account was debited and salary also debited same month. We contacted discovery and they said the account will be billed in advance and not arrears. It ia now 2020. We have cancelled membership as of end of August 2020 to go onto another medical insurer. However the company has said that they deducted at the end of this month for this month(August) I have called and had a virtual chat with discovery. And they have not been of much help. The employer says consult discovery. Discovery says consult employer. Such pathetic service as I have been ripped of for R2800 for discovery medical aid and I have still paid another medical cover. This is ridiculous. However the employer indicated that discovery has advised end of August payment is for August. THEN I SHOULD BE CONTACTING THE OBADSMAN FOR DISCOVERY TO HAVE THIS INVESTIGATED FURTHER AS I REQUIRE MY REFUND.
