Caller ID said: "FBF"

Called number back - mail box if full!  What a surprise - how do we get the phone company that lets these assh0l3's keep bothering the public?

FBF?  I can think of many choice words for F-B-F.  Wish these jerks would stop calling.

Monday evening and Monday night....answered twice and whoever it was hung up.  So I started letting the answering machine get it and they just hung up.  By 9 pm I starred 69 it and reversed looked up and found out it was this number 414-877-5655.  Who are these people and what do they want?

Called Sunday afternoon. It says just "FBF" Didn't pick up
