Spent three hours in the store to change my already existing ATT number to a new data plan. The oily store manager added services to my account that I didn't need telling me that they made my bill cheaper while they actually cost money. Also promised me credits toward my bill for the long wait which I never received. All around terrible experience with this store. I love ATT, but the experience in this store and the hours spent on the phone canceling extraneous services to my account have made me think twice about my carrier. Don't use this store for any reason.
