They call and hang up after I say Hello. Once I heard someone on the line when I answered. A guy asked for someone I don't know. I said "No" and he hung up.
i have received very similar calls from this number. I signed on for Caller ID and the name given with this number is: Chevy Chase. I called my phone company who suggested calling the Federal Trade Commision (FTC). The FTC reported that they cannot investigate unless they receive several calls with a complaint...so I suggest you and anyone else receiving these calls, also call the FTC (877-382-4357) so that an investigation can be done.
