Poor service - understatment

Really disappointed at the service I received from Bankmed. I submitted a claim along with a receipt indicating that I've paid the full claim. When bankmed assessed the claim they were only will to pay 30% of the claim. My frustration is that even though they paying 30% they have decided to pay this amount to the healthcare provider? I submitted the claim twice; the first time they claim the codes were not visible or incorrect codes were provided. Nobody contacted me to assist with the claim I was left to my own devices. I subsequently enquired on this as the amount was to be refunded to myself, to date Im still waiting for the funds. This is the second incident I've experienced with bankmed claims its really disappointing and throughout this process not a single consultant contacted me to clarify issues.
