So over having to ask for Claims to be paid that should have been paid months ago!

I have been with Essential med since May 2017. I had to go and see an Gynie in January 2018 and sent my documentation around the second week of January 2018. I am suppose to have received a refund within 21 working days. It has been about 35 working days and I still have not received the money. Received an account for doctors visit from October last year to date. I went to a network doctor and confirmed that they will be covered with both the doctors room as well as with Essential Med. Just to receive the account showing that they were not paid from October 2017. I have tried my best to report this to Essential Med and have had numerous fights but they keep on having excuses and do not attend to my issues. The other day I called to speak to a nurse on a Friday to ask for Medicine to be approved. I was told twice that someone will call me back and no one even called. I am so over having to struggle with them to pay my claims and to get feedback. Seriously considering moving my insurance back to Oneplan
