Approved Claims NOT Paid Out

I have complained several times about this problem and it seems that there is no progress on improving this problem. I receive correspondence that my claims are approved and will be sent for processing. On several occasions, these approved claims are not paid out. The providers then harasses me for payment. I have to then contact Bonitas, spent 15+ minutes on the phone on my expense explaining to the consultant what the situation is. There is usually no record of any thing that I explain and I have to get reference numbers, practice numbers, dates, amounts, etc. If I received approval for the claim, surely there must be record of this on the system. PLEASE UPGRADE YOUR SYSTEM TO AUTOMATICALLY PAY OUT CLAIMS THAT HAVE BEEN APPROVED! It is really a time and monetary burden to remind Bonitas to pay out claims that they don't know of, but already approved and it shows complete maladministration.
