Canceled my Cingular plan long before they merged with AT&T, now these people call me and say I owe money. I knew it was a scam by looking up the number they left for me to call, and when you call back it automatically goes to some lady named Gracie's mailbox. I called back to argue over the "bill" and she was completely rude. I even explained to her I just lost my job, so she said she'll send me the bill and I can do whatever I like with it and hung up. Beware!
