It isn't a scammer.  It is a legitimate health care insurance coordinator sponsored by employers for retirees and their dependents and beneficiaries.  If you had a spouse or parent/guardian that was entitled to benefits you may want to call them back as you may have benefits.

They are legit.  If you don't respond, you may loose your retiree health and Rx insurance.

However, the call shouldn't have bee the first you heard about them.

OneExchange is legit. If you have retired from a large company that provides you with health insurance, the company may have hired them to update your policy choices. I have dealt with them recently.

Apparently, this was legitimate; not a scam call!  Very confusing!

There is no way to edit my original post.  Apparently the company was Towers Watson and it was about something called OneExchange. I still believe it is a scammer using the name of that company. I'm looking into it.
