i bought a cellphone from craigslist, and i was called at&t check the IMEI number, everything is good, so i bought it. after 2 weeks i try to paid my at&t bill, i find out there is a Telesales CPE Chargebacks for $334.69. i call at&t and they told me this charge is for my phone, because this phone who bought it from at&t is dispute from his credit card, so at&t just charge the money for who using it. my question is can at&t charge me for the phone? thanks
