Got a couple calls from this number as well. Didn't give my number out - especially since it's a cell phone with limited minutes. Don't give my number out to just anyone either. Common thread with multiple unknown calls I've been getting is responding to pop up solicitation for a free IPod which I removed my information from in backing out but.... evidently they already captured my e-mail address which I've gotten a flood of solicitation e-mails - but no free prize coz I backed out. Feel like they owe me what they claimed was free but had an additional purchase attached to it OR, they're getting my number from anyone of the on-line job soure websites I've logged onto. In either case, they're unwanted.

I just got a call as well, no message left.  I don't enter any contests or look for free stuff so, I don't know how they got my number.  Second call I've gotten in as many days.  The one yesterday was from Illinois. Same thing, no message either.

Yesterday I received a call from an unknown Illinois number.  I did not pick up and they did not leave a message.  Today there were two attempts from 650-419-5535.  Same thing - no message.  Similar experience to another responder here.

I received a call from this number at 6pm. Caller did not leave a message. I have been in the job market but have not entered any contests.

I called the number back and it is from either looking for a job online or looking to further your education. you have the option to be put on thier no call back list
