Called my DNC registered landline. No voicemail. Just one of 10 scammers I'll get today.

The Do Not Call registry has no ability to stop illegal calls from scammers in India or Pakistan, Russia or China. The number on your caller ID was most likely spoofed (faked) to look like a number in the US.

This caller left no voicemail! If you don't leave a message, it must not be important...then you must be a scammer!

Repeat call from back in July. No voicemail.
I used *67 to call back. "We're sorry. The number has been disconnected."
