Can't be legit -- tried calling "BEDMINSTER PA" back and got a message saying "Number not in use" (!) That suggest a scam call using a spoofed #. Do NOT pick up!

Tried calling "SEWICKLEY PA" back; weird recording offering a "savings plan upgrade" (?) -- gift cards to (unnamed stores) or discounts on (unknown) dental office visits (!). NO mention of who's behind this, or what you're going to have to give THEM.... Suspicious!

Caller ID said "MCKEESPORT PA". Tried calling back (within a minute or two of the call coming in!) and got a recording saying the number was not in service! Clearly a spammer using a spoofed number!

Another call from this same area code and caller ID as yesterday. No message this time either. Clearly spam and possibly harassment.

Another call from "HARRISBURG PA" (or should I say "HARRASSMENT-BURG"?); another call which went to voicemail but where no message was left; and clearly another scam of some sort.

This call came in about 2 hours after one from 412-556-0189; caller ID "SR HEALTH PLUS" was similar to the first call, which was "SR INSURANCE" so guessing the same spammer and type of call.

No message left even though call went to voicemail. Didn't recognize the number or the caller ID, which came up as "SR INSURANCE". This does NOT appear to be this company's number because they're in Georgia, NOT Pennsylvania. Clearly some sort of scam.

Caller ID just said "DUMONT NJ" (yeah, with a bunch of space in the middle like that -- that's often a red flag that it's NOT a legit call). Didn't recognize #, I'm fixing that (you're welcome).
