Terrible customer care

I was rushed to the ER in August, treated and discharged the following day. Discover has rejected claims, including scans and X-rays sent by the hospital. When I follow up, they are pushing the blame to the hospital or consulting doctors to fill out forms for them to pay. I have received no help from their agents when I try to get clarity. For all the monies deducted monthly by Discovery, it’s really not worth the hassle.
