Noted on my November ATT phone bill was a charge of $15.88 for "Enhanced Services" when I called to complain about the charge, the respondent gave me the date the service was signed up for, my name, birth date, e-mail address, and home address (information that could have been illegitimately, and or erroneously obtained). She also told me that I was responsible for the existing charge, despite the fact that the service was being canceled as of today. When I explained to her that I did not sign up for this service, and did not remember signing up for this service, and asked for some record of signing up for this service she was unable to provide specifics of the same. I am asking for a record / or documentation ( something other than my name, address, date of birth and e-mail address) of my registration for this service before I agree to pay the charge. I feel and believe that requiring me to pay a charge without being able to adequately show proof of said charge, or origin of such a charge, is an unfair billing practice. Again, I am disputing; and refusing to pay this charge, unless your company can show me where, when and how I signed up for this service; and explain why I should pay what is the equivalent of a one time fee for a service I never used or had any intention of using. It seems to me that this constitutes an "unfair billing practice" that I intend to make a referral on!
