(WPRI) – Many people share the experience of getting a phone call from an unknown number, answering that call, and hearing one of those automatic robo-voices on the other end.

Americans receive billions of these robocalls every year. Even if you’ve signed up on a “do not call” registry–you’ve still probably received them.

Eyewitness News consumer reporter Susan Campbell spoke with Alex Quilici, the CEO of the company YouMail, about how to stop these unwanted calls for good.

“My company YouMail replaces your voicemail with a call management solution, which recognizes robocallers and plays them ‘this number is out of service,'” said Quilici, describing his software which can help consumers block robocalls.

Complaints regarding robocalls to the Federal Trade Commission have spiked fifty-percent this year. It has been reported that in the first four months of 2016, Americans received about 10-billion robocalls, trying to sell us something, or even scam us.

“These calls are abusive and they’re illegal,” says Lois Greisman of the FTC. “Some of the calls are fraudulent. They are offering something that doesn’t exist.”

Even if a consumer has signed up for the FTC’s “do not call” list, it’s not much of a deterrent for scammers. This is why software such as YouMail and another one called Nomorobo–which detects robocalls and hangs up before the consumer answers them–are great options.

The cheapest, and most low-tech option, however, is just never answering phone calls from unknown numbers.If you have a consumer problem you need help solving, contact our Call 12 for Action center at 228-1850, Monday-Thursday, from 11 a.m. to 1 p.m.
