Just called me on my cell, did not talk or leave message. I'm over telemaketers...

called my cell and hung up before I could answer it.

It's a Nova Scotia area code, which is an unusual place for a telemarketer to phone from, but I suppose they can phone from anywhere, and at any rate, it's obviously some sort of spam because when I googled the number several pages of posts came up about it.

If I don't recognize a number I wait to see if they leave a message. If they don't then pfft - that's the end of it.

(902) 203-9997 called me on my cell in FL at 1:08 P.M. EST Friday, May 15, 2009. No name available with the number so I didn't answer. No message left, and when attempted to call back got this message, "The number you have dialed is not a working number, please check the number and dial again, Alltel 42-P"

They are calling me too, also on my cell. they don't talk, just hang up.

Who is this?  They keep calling and hanging up.
