Also got a call from "301-374-8834 Maryland" on Saturday, May 13, 2017 at 6:40 PM.  I didn't bother to answer as (1) I do NOT recognize the number and (2) I was resting after having a long day.  I figured it had to be another telemarketer/scammer again1

I received a call from this number. My computer recognized it as a likely spammer/scammer and disconnected the call.

i got a call from this number but did not get a message.

Missed call and no message left; typical scammer MO. CID Waldorf, MD. Even though I live not far from here, I don't know anyone from Waldorf. Mr Number reports that several Indian scams use this number for the student loan scam and 'senior benefits' scam.
Best to not answer and never call back.
