No connection between the caller ID: "SUPPLEMENT CARE" and this # as far as I've been able to determine. Got a similar call yesterday from "MEDI SERVICES" -- only they are NOT in the 412 area code! Guessing it's the same scammers because only the last 4 digits were diffferent....

Call came in ~9:30 AM. Didn't recognize # OR the caller ID: "NTDS". Picked & hung up at once as a precaution. No useful info about name on Google. None at ALL about it in conjunction with #. But DID find at least 7 sites like this which already had negative reports about #!

Caller ID just said "CARNEGIE PA" (yes, with space in the middle pushing the text to the edges of the screen). Some woman named "Julia" asked for me by (first) name but hung up when my husband asked her to leave a message. Suspect spam of some sort....

Caller ID said "MEDI SERVICES". Apparently a real business but this is NOT their #. They are in MA & would NOT be calling from a PA area code! Suspect spam using a spoofed caller ID.

No message left by "Name Unavailable" even though it went to voicemail. Tried calling back on a "safe" phone & got the "We do not recognize" this #" message. Well I don't recognize YOUR # and mostly neither does Google!

No message left. Caller ID said "MEDICARE 4 YOU" (apparently a WISCONSIN based business). Tried calling back on a "safe" phone -- only got a recording saying "Number not i service!" Clearly a scam call!

Caller ID said "INSURANCE LIST" (!) NO apparent connection with that & the # on Google. As for a search just for the #? Three overseas sites with fake sounding names they told Google (seriously, someone in Lesthoto is named "Alaska"? Yeah, pull the other leg too....)

Accidentally called "MORRISVILLE PA" back to get voicemail (only there WASN'T). "Gail" said it was the "Medicare Enrollment Center" but couldn't say why the caller ID was different OR why no message was left. Now reported to Medicare.gov (who said they DON'T make cold calls).
