They just called my name a few times... Caller ID said Eugene from Oregon...

Same here, new prepaid pain medicine, yea right.

Just received a call from that number. I did not pick up.

I don't answer callers I don't recognize. They didn't leave a message.
This is another CallerID4U Landline scam. CallerID4U Is a telecom that hosts scammers in the Pacific Northwest in revenue sharing agreements.
Google it.
In the mean time it's in your best interest to just ignore callers you don't know. If you do answer you've given away your number is valid, they know the time of day you can be reached. They know your sex and approximate age and all you've said up to this point is Hello. If you answer any questions they add it to their database of know information about you.
