Who called from 7737678388

Name says Mildred Cummings?  When I called some guy answers and says "Hello".  They call all the time I don't know who it is

CALLS NEVER LEAVES ANY MESSAGES, CALLER ID SAYS MILDRED CUMMINS

Calls at least once a week or more. Caller ID says Mildred Cummins. Finally added to my block caller list.

Looked up phone number and it belongs to a Mildred Cummins in Chicago....lists her age at  99. Either she's confused and just dials numbers or it is some sort of a scam. I get this call a few times each month......got one today but I never answer call since I believe it to be a scam of some sort.

The most likely explanation is that her number is being spoofed.
