I tried calling MultiPlan.com's various information lines found online, to find out whether MultiPlan Corp calling from the Maryland phone number 301-2986-4766 is affiliated with Multiplan, Inc./Multiplan.com. unfortunately, there's no one manning any of Multiplan.com's phone numbers. I give up. They were wanting info on a doctor I've never heard of. As far as I'm concerned, we don't need to do business with them, so I'll be blocking their number from reaching us.
