Who called from 5039028279

hung up when answering machine picked up

I answered, they hung up, but they call my cell frequently.

Same thing - started getting calls twice a day on my cell.

This number called for the first time last night, with caller ID as "PACTEL". They left no message. We have also received calls from 503-902-8287 and 503-902-8477.  Pests. Violation of 'DO NOT CALL.'

Has called multiple times and left no message.  This is from an Oregon number.  I live in KY and do not have any business relations in Oregon.
