MY INFO GUARD LLC. illegal charges Clearwater, Florida

While looking at my phone bill for the first time instead of just paying it, I saw unauthorized charges on the August 2009 bill. After calling AT&T about the charge, they informed me that the charge had been on my phone bill for the last l8 months at $12.95 per month for a total of $233.10. AT & T also told me that I would have to call MY INFO GUARD LLC. about getting a credit. After calling MY INFO GUARD, they told me that they would only give me $25.90 for two months credit. So now I'm out $207.20. How can they get away with not giving me full credit for all the unauthorized charges.While looking at my phone bill for the first time instead of just paying it, I saw unauthorized charges on the August 2009 bill.
