When I was a cell phone company care rep we had the Palm Treo scammer. At the time that was the most expensive phone we served and sold. What they would do is call a customer and trick them into giving verification information usually by pretending to be our collections department. Then they would switch the address on the account and order as many of these phones as they could billed to the account. Once they had the phones they would get them unlocked and sell them on eBay. I can't figure how they never busted these guys. They just kept going to the well. The first time I got the guy on the phone trying to order the phones I was onto him in about ten seconds flat. I called the customer directly while I had him on hold and got voicemail. The name on the account could have been male or female. The voice message was female and he was male. I asked him about that and he hung up. A few weeks later I get the same guy again on a different account. I recognized his voice from the get go. This time the closet vigilante in me wants his ass. I alerted everybody and tracked the account for the rest of the day. Noted the account. I was livid when some idiot rep ignored the notes and put in the order for him anyway. Thankfully I'd made so much noise the Business Security department stepped in and shut down the deal before it could process further.
