me too. ID said "Fresno, CA"
I never answer calls from numbers I don't know. if they don't leave a message, I look them up and end up here, more often than not.
Called offering to lower my gas bill. Don't press any buttons or say anything when they ask - that proves you're a real phone number. They've called from different numbers about 6 times in the past 3 days. Besides this, I never get scam calls on my cell. Why now?
