Any idea how many robocalls we get each month? Here in the US, it’s 5 billion a month, all told. Some people place their phone numbers on the national Do Not Call list, at donotcall.gov. Most of the bad guys ignore that list, but it helps a little.
And many of us, in an attempt to stop the madness, wait for the instructions in the call as to what button to push to remove ourselves from the call center’s lists.

Hope this helps!
