Who called from 5030215479

Received phone call asking for my mother-in-law, who passed away several yeas ago. When they asked if I was (my m-i-l's name), I answered "no" and by the time I tried to let them know that she passed away (so that they won't try and call my number again), they had already hung up. They did not identify who they were calling for or why. The woman had a rude and repulsed tone of voice.

Answered but no one responded and then it hung up.

2 hours after the call from 503-021-5479 I received a loan telemarketing call from 630-914-8915. The first call must have been the probe for a live answer.

Have gotten three of these calls ...all from a woman who can barely speak English, but assures me we have spoken before...not!

Received a call from this number, picked it up, but said nothing.  Was waiting to see if it was a person or what?  No voice, no nothing, then a beep, and the line went dead.
