It is a VIOLATION OF FEDERAL LAW for telemarketers to make "robocalls" your cell phone, yet that's exactly what happened to me just now. If YOU get such a call on your cell phone, insist on talking to a live person and then tell that person that the call is illegal.
Can't be a bill collector- I don't have any outstanding bills, especially nothing associated with Fair Haven- there's nothing there!! Called my cell as well, but didn't leave me a message.
