Service is horrible!!!

I have been struggling with Bankmed for about 3 months - they put claims through my medical savings account for something I have Insured Benefit. This happened not once but 3 times!!!! Then I called in to get this fixed and 3 weeks later I have spoken to about 10 people and all of them are *********** and hasnt solved the problem as yet and everytime they say they will call me back and no one has ever phoned me back. Last week I noticed that they put through the one claim again, I called in - they said it would be fixed. Then today I get a letter from Bankmed stating that I owe them money. I phone in again, for the 11th time, only for the lady to tell me that they paid the provider twice, the one amount was paid in error. WHY SHOULD I PAY ANY AMOUNT TO BANKMED IF THEY PAID THE PROVIDER!!!!!! And why should I phone Bankmed to get a problem solved if the mistake was made by them to start with!!! I am sick and tired of the poor service I am getting. I pay more than enough for my monthly premium and I expect the service I am paying for!!!! This is unacceptable!!!
