Same thing just happened to me. A woman in a foreign accent asked, "Is this [my name poorly pronounced]?" I said, "yes" and then she immediately hung up. Creepy. If you call back an automated recording says, "the mailbox you are trying to reach is not in service"
Based on these comments, I'm probably going to just block the number.
08/29/16 @11:50am - rec'd a call from 301-451-7065 asking for the owner. Not in, may a take a message? He just HUNG up on me! Bogus call, no doubt! Someone with a deep foreign accent and the background noise I heard sounds like a calling center.
The caller said he was from Mayo Clinic. The person for whom he was calling wasn't expecting a call from them and didn't know why they'd call for her. She didn't get to find out because the caller hung up while I had him on hold.
Just got similar call at workplace. Registers on ID call as HLTH HUMAN SVC. There is no such company listed. This is apparent identity theft in progress verifying information.
