I have had multiple calls from several Oregon based numbers. I do not answer them after the first time I called back learning it was a "survey". I have placed 3 different Oregon numbers on my block list for my cell phone and only have so many available for use. This is becoming harassment.
I got a call from a telemarketer the other day, not this one, and the number showed up on CID so I returned the call, over and over and over and over and over...... for about an hour. Sometimes I would get a busy signal, sometimes it would ring a number of times and they would disconnect, once I got a message telling me "the action you requested can not be fulfilled a this time." They have not called me back since.
