Who called from 3217666809

With these type of callers, I add the number to my contacts as "Unknown 1-20" then save.
Then I go to my contacts, open up the "Unknown number", then open up the menu (usually at top right hand corner of screen)
then I check the forward all calls from this number to voicemail. That way my phone never rings when these spammers call.
Hope this was some help to you folks.

Me too.

A shame you couldn't forward it to another junk caller. < lol >

Calls every 2 or 3 days rings twice and hangs up.
