Hey! Good news, the internet is my friend! 1-800-331-0500 That's how I talk to AT&T. Any idiot who can type Google can find out how to talk to someone at AT&T or walk into their store. Stop blaming other people for mistakes you make. It sucks, yea. But you either say "Damn, I should have checked first, Oh well. I like it enough so I'll stick with it" or "Damn, I should have checked first, I can't use this. I'm taking it back" That's your job as a consumer. You can put down your "Destroy Corperate America" signs and start doing something useful now.
Walk into the store and do what? I was an ETF, AT&T had a team of trucks buzzing around my area. AT&T called me and said "Sir, we know that the cell coverage in your area is bad, and we have no plans to fix the problem, have a good day." That's not me coming down on corporate America, that's me saying AT&T is a crap company.
