Still waiting for feedback on claims...

I submitted three claims on the 10th March 2016 and up until today I was only paid for the one. I have on numerous occasions requested feedback with regards to the progress of the two outstanding claims and nobody is getting back to me. All my emails are being ignored. If the three claims were submitted at the same time why was I only refunded for the one on Friday 8th April 2016?? Since signing up with Essential Med I have had non stop issues, I have had to change Dr's twice because I was told that they no longer accept Essential because of payment issues. So I had to pay out of my own pocket on more than one occasion and now I am made to wait for my refunds and nobody has the decency of getting back to me with feedback.
