Who called from 7242130821

We receive multiple calls per day from this number. They never leave a message and if we answer (rarely) there is no one there.  Over and over, at least 6 times per day to our business number.  Grrrrrrrr.

Same situation as poster named annoyed- Multiple calls a day- never anyone there. Drives me up a wall!!!! This is a business they are calling.

Calls repeatly and hangs up.  Calling a business

Multiple calls per day showing that the calls are from Imperial, PA.  No voice messages are ever left.

We receive several calls a day on our vm with no message left.  They stay on the line for a few minutes - you can hear some type of electronics in the background but never say anything.  Very annoying.  Please stop...
