There is an app that you can put on your phone call "Calls Blacklist" If you have a number that keeps calling and annoying you then add the # to the Blacklist and you will never get the call again. The app blocks the call.
got a call from this number. picked up first ring. immediate hang up...
I know the reports are from debt collector; I have no debts.
Glad I ported this number. Ditch your landlines. Blocking and reporting is easier on cell phones.
