I've gotten about six calls from this number. A man claiming he works for Comcast and is coming to pick up my modem. I've called Comcast; they doubled checked my account confirming I don't owe anything. They had no record of anyone scheduled to come take anything. The real Comcast told me to ignore it.  I'm getting creeped out. The same guy left a suspicious pink slip on my apartment door (at about 9pm) with 3 numbers on it. None of which can be traced back to Comcast....
