ETTA MAN THEY CAN GO F... THEM SELFS THEY CALLED WE DIDN'T IF CALLER ID DON'T SHOW THE CALLERS  # HI/SHE CAN GO SUCK ON A MUSS

I never answer calls from  numbers I don't know.  
Why would I want to talk to unknown callers?
If you don't have caller ID, get it.

I have gotten two calls in 4 days from them.  I let the answering machine get it and of course they won't talk to it.  Caller Id says Unknown.  I am on National Do Not Call list.
