We all get them, unknown calls. I’ve stopped answering them. They leave no voicemail. Probably a robocall.  A computer-generated call when answered goes to a call center. Everything from solar panels to car warranties, these unwanted and unsolicited calls are on the growth.  There is hope, however.



Robocalls are a rising nuisance in the U.S., and many of them are illegal scams. The call-blocking company YouMail estimates that there were some 4.7 billion robocalls placed in the U.S. in May alone.
