I signed up for insurance with principle advantage limited benefit program under the impression it was a legitimate insurance company since it seemed like it was part of health care .gov. But, I tried to use my "insurance" and heard the lady processing my info say how odd the plan number sounded and that nothing was coming up in her computer that recognized it as a plan number. I feel so taken advantaged of. I just went online and cancelled my plan. They better be shut down, totally a scam.
