1-800 number scam

I opened my AT&T phone bill and seen it was higher. This company claims that I "signed up" for a 1-800 number. Which never happened obviously. Then I called and talked to someone that could barely speak english that said I signed up on-line. I asked her to repeat my soc. sec. number and was told they don't require that number. So anyone could have done this. Beware. You don't need personal info to order this and be billed. Just watch your phone bills. Oh, and yes I was told that I can cancel this fee but I would have to pay for this months bill! which I am not.
