As of November, U.S. phone users had received just under 54 billion robocalls this year, surpassing the 48 billion that were received in all of 2018, according to YouMail, a private robocall blocking service.
The problem has reached such epic proportions that, according to a nationally representative Consumer Reports survey, 70 percent of U.S. consumers say they won’t answer the phone if they don’t recognize the caller's number. Sixty-two percent say they let most calls go to voicemail.
