Non payment settled since April 2015 outstanding

I received a bill from my doctor that was not paid in April 2015 which was sent to Essential Med to be paid. I had believed the account was sorted. Only to receive a statement in August 2015 that the account has not been settled. Email was sent to Accounts and Finance department at Essential Med on the 20 August 2015 and again on the 03 September 2015. I received a reply that I would be contacted within 72 hours. It is now the 8th September and no feed back. I want to know why the doctors bill was not paid since April with no explaination and why no feedback up to this point has not been done.<br> Policy Number: *** <br> Things only seem to get sorted when the consumer has to resort to social / networking / online complaints.
