Called and left no message

I've registered a complaint with the Federal Do Not Call website for this number:
https://complaints.donotcall.gov/complaint/complaintcheck.aspx

Caller ID said SAN FRANCISCO CA
I called back, was Fraternal Order of Police

BOGUS... see:

Fraternal Order of Police scam....

I swear these guys change their number more than their underwear.
No point reporting them - the numbers they use are spoofed.
They call at least once per day. I guess this is another number I'm blocking.
This is getting tiring.

You don't know any underwear jokes ?

The soldiers of an infantry unit had been in the field for two weeks when the Sergeant announces, “I’ve got good news and bad news. First the good news. Today we’re going to change our underwear.”
The troops start cheering wildly.
“Now the bad news,” continues the Sarge. “Smith, you change with Jones. Andrews, you change with Murphy…”
