I just got a new cell phone. On day 2 they started calling. Uugh!

Called looking for a woman with a name that is kinda similar to mine, I hung up. Caller ID said Rockford, IL.

they keep calling for some one that had this number two years ago. they have been told she does not have thei phone anymore and they said she must work for my one man company and i need to put her on the phone.  they will not go away and call 3 - 5 times per day including sundays.
