The worst medical aid scheme ever

I submitted a claim with bankmed 3 weeks ago and it hasn't been attended to. The first week when I called them they said they made a mistake because the money was supposed to be transferred to my bank account and not of the doctor and they apologised and said they were rectifying the problem. The following week I get a message that it was rectified after I called them and they promised that I will have the two refunds in my account. I just called them now trying to find out what happened and they tell me that they couldn't pay the second claim because the first claim bounced back. No one called me to find out if my banking details have changed. The answer I am getting is that I should have gone to the website to update my banking details. they just simply left my claim and not put it in for payment because the banking details were not correct. When I looked on the system they had both my two banking details and they didn't even bother to call me to find out if they were correct. I am just so irritated with bankmed if I had a choice I would have cancelled my membership.
