dang.
They had something like this for beepers, you'd get a beep and a seemingly regular number shows up...you call it because you're like "who the heck is this?" and you get a recording saying your service has been upgraded. then on your phone bill you get charged $10. I fought hard to get those charges lifted from Bell Atlantic and they did, but this is way shady. (what...beepers and bell atlantic wasn't that long ago)
thanks for the tip.
