This came to my cell phone, but didn't leave a message. I'm reporting a complaint to DoNotCall dot gov. Let's all do this so we can stop this person.

Called my cell phone. Showed up from Iowa. I pressed "1" to get a person.  It was not an American.  Wanted to save me some money on my credit card.  I asked where he got my cell phone number and he said "Experian".  Like, really??  I hung up on him and blocked the number.  We don't carry balances on our credit cards.  I called the number back, and the call could not go through, so it had to be a scammer!

They called my cell phone and didn't leave a message. Caller ID said it was from Ames, IA.

Unknown company/caller, but the forum timestamp here suggests it is now an active spammer (very recent posts) performing a 0-day hack.  Number is immediately "invalid" upon callback attempt.

Yep. AMES, IA.  I answered, but got no response.
