Lack of response and actioning requests

I have been phoning Discovery Health for a simply claim reversal to be done since the 9th of July. I have phoned everyday and have been on average on the phone for 30 min a day sometimes longer. Nothing has been done to resolve this issue. Discovery quick to take your money every single month, but as soon as you logged a query they never phone you back when they promised and do not deliver on their promises. This is really bad service.
