I never had a problem either until you try to anything outside of the ordinary. My wife needed some special treatment it was a nightmare to get approved I wasted hours on the phone to be told that the procedure was through another insurance company my company hired for this special procedure. They made so many mistakes I had to call once a week. At one point I had a 4 way conference call between both companies and a special hr person from my company to get this shit sorted out.

That is what pushed me to socialized healthcare private insurers can get fucked.
