NOT PAYING FOR MY RIGHTFUL BENEFITS

I have an unsettled claim that has been rejected because the tariff code used by the service provider is incorrect or unknown to Bankmed. I have been calling since I became aware of this since late February 2015. I call the service provider in hope of getting the correct tariff code they told me that is the one they use and all other medical aids accept it. Bankmed then said I should send them the bill, which I did only to call the next day to find out the person from Bankmed that I sent to didn't forward it to the claims department. I resent, and instead of the claims department loading the tariff as the call center agent said they would they processed the claim as is and Again -Obviously it was rejected. Now I am getting sms's from the service provider because of the unsettled bill. Bankmed agent said he would call the service provider to explain, which didn't happen. I called again today twice they said they are investigating and they can't say when I will get feedback, its been escalated to team manager. <br> How many times do I still have to call? I do my part of paying monthly they should do theirs and settle the claim!
