Shocking service from Discovery

I have been struggling to get Discovery to rework and refund 2 claims for more than a month. The service is terrible. They put the phone down in your ear when complaining or have a nonchalant don't care attitude. After giving them clear instructions they still made errors. A refund was eventually made to the provider whom I already paid as indicated on the statement in the first place. I would not recommend using this medical aid. There is no service, they ignore emails or respond without answering the query.
