I need to call in every month for Cpap supplies. I have to stay on the line waiting 20 min or more and many times they hang up and have to start all over again. I have had to go to the MedCare facility to order the supplies because they don't answer the phones. I am trying to call the corporate office to give my constructive testimony, but I can not find the correct phone number. This never happened when I was with Florida Blue. I hope this gets corrected since that is my only complaint.
Thank you
