Didn't answer this unknown number - no voicemail was left

Scumbag recording "Stop what you're doing right" yelling.

Suck my balls monkey boy.

Harassment via robo recording.

Stop what you are doing right now (yelling) and listen to this unique business opportunity I have for you?

Block them.

These guys keep calling me, and give me the "Press 9" option for "I gaurantee you will never hear from me again".
The first 2 times I just hung up.
Then I started pressing 9. This is the second time I pressed 9, they keep calling me!!!!!!!
I called back to yell at someone, but is just more automated marketing system crap. I want to punch these guys.

As long as people keep answering, they will keep on calling.  Ignore them. block them and report them.  The good guys will win in the end!!!!!!!!!!!!
