Have been receiving calls from this number (360-529-6902) and 425-390-8961 for months. They never leave messages and I refuse to pick up. They're pretty relentless; at least 5-7 times a week. I'm also on AT&T. I'm going to attempt to block them from my account page and also complain on do not call website.
Good luck and keep fighting the good fight! No means no a-holes!
I called them back since they left no message...an answering machine answered (a marketing call from a commercial entity) and allows you to hit "1" to be placed on their do-not-call list...
