Revenue Assist keeps calling me.  They hang up as soon as the answering
machine is going to pick up the call.

keep receiving calls from revenue assist.   hang up as soon as answering machine starts.  how can I block this caller

They called, from "Education Authority.com" and "Gladys" said they were responding to our having gone to their site. Total BS. I called the number back, no answer, ever. I hope these %^$^%$^%$heads rot in hell.
