Who called from 4153636608

Called just now, I didn't answer, and they left no message!

Same here call and no message.  Looked it up and it said land line in san francisco.

wow, must be a new collections number with all the new notes here. just called and left no voice mail.

i called the number back and it sent me to a voice machine that said i had reached the removale line. so if you call it back you can get them to stop calling.

I have received 2 calls from this number with no message being left.  After calling it back, I get "you have reached the automated removal line. press 1 if you would like to have your number removed."  removed from what??
