There are 2,700 robo calls made every second in the US. These scammers find sneaky ways to get through to you.
Dozens of apps help block the calls from your cell phone, but we found one app that gets back at the scammers and even prevents them from making another fake call.
"It puts a smile on my face to hear the telemarketer get aggravated, you know. It's like, what do you think you're doing to us people? We have lives, stuff we're doing. Nobody asked you to call."
It not only stops your phone from ringing when a scammer calls, but actually answers on your behalf.
