I love number in display; "120-1234567"
Called but then hung up.
I would talk with them until they hang up.
They stop calling faster, and leave me alone
Rec'd call from 210-123-4567. We usually let unknown callers first go to VM and after I've researched the number, we block it when I confirm it's not something we want to answer. While I hadn't yet looked closely at the number, I saw "Name not Found" and decided to send them the message that I did not want to talk with them, without talking with them. So I disconnected. Then I noticed that the number was clearly spoofed.
We have noted with the recent arrest of fake debt collector William Scott & Assoc. scumbags, the fake debt collector calls had disappeared.
