Who called from 6104214642

numerous calls every day unwanted

I get calls from 610-421-4642 almost daily. I'm not sure if this is one of the numbers that just hangs up, as we get several each day--some of them are listed "unavailable" or unknown or whatever. I have returned some of the numbers to see who they are & I get a message stating "this is a non-working number. It's very annoying. Wish there was some way to stop this.

i answered........they hung up.....

inaudible, whispered message left on ans. machine,.

No one on the line -  picked it up after three rings.
