Male VO: If you have a telephone, robocalls -- may be ruining your day.

If you answer the phone and hear a recorded message instead of a live person, it’s a robocall.

If the recording is a sales message and you haven’t given your written permission to get calls from the company, the robocall is illegal.

When you get an illegal robocall, here’s what to do:

Hang up the phone.

Don’t press one to speak to a live operator and don’t press any other numbers to get off the list.

If you press any number, it will probably lead to more robocalls.

You might consider contacting your phone provider to see if they can block calls from the number. But they may charge you, and telemarketers frequently change their caller ID information.

Report illegal robocalls at FTC.gov, or call 1 877 FTC HELP.
