Poor service and no response on claims

I sent in a claim for my daughter's pediatrician visit 12 days ago during the course of the past few days i have sent over 8 emails with regards to the claim, each time receiving different excuses why the claim is not being paid back to me, the excuses has varied from not able to see the amount, the statemeny does not state the patients name, the date of the consultation is not stated ect please note that all the info that are used as reasons for not paying me back is clearly stated on the statement, this is the original statement as received from the doctor's room this is not a scanned in copy so how can this not be clear enough, i was supposed to receive a response from the claims adjustment department accoring to their automated email system between 2-3 days, and still although once again sending the complete statement 4 working days ago still i have yet to receive a response, i have also requested on numerous emails for a consultant to contact me but also with no luck, this money is owed to me and i feel agitated and disgusted with receiving no assistance and irrelevant and unsubstantiated excuses why the claim is not paid out when clearly all info is on the statement.
