Got same call as reported for 520-944-4451. Wants me to go to www.grant100.org for government money.  I tried calling the number
520-944-4450 back and it says it is a non-working number. How can they be
making calls from a non-working number and why can't the phone companies stop it!  I reported to Verizon that I don't understand how a non-working number can show up in my "recent calls" list.  They weren't able to help.
