My hatred for scammers knows no bounds.
All though just get insta-blocked. Some leave voicemails but it's always a robot. Those get insta-deleted.
In fact, during election times it gets worse, I got an unreasonable amount of texts and emails telling me to go vote for the shmuck they want to win. Guess who didn't vote for them? Yep, this guy! Now all of those numbers and emails got blocked.
If it's something truly important, you'll leave an actual voicemail with a number to call you back, or you send snail mail.
