Who called from 5032018209

I just got a call from the # you have listed. I don't know anyone in Portland, Oregon. Nor have I ever. Another # I'd like to report is: 503-250-0519. The other is the one above. Both times left no message.

They called me, I answered since my work calls are currently being forwarded to my cell phone too.  They hung up when I answered, and when I called back, all I got was a busy signal.

Same happened to me just now, happened also two weeks ago. Callback goes to a busy number. This is on my AT&T cellphone.

Just got a call also, I live in Huntsville, Al. I tried calling back but seems it doesn't allow incoming calls.

I got mine at 10:31 but I didn't pick up
