Re Think Possible_translated means it was possible but AT&T needs to rethink it

AT&T has the worst customer service! I currently have DSL which is way too slow, but live in an area that doesn't have other viable options. I have tried to sign up for U-Verse previously and it showed address not serviced. I received a postcard in the mail, to my address, with my name on the card. It states AT&T U-verse is now available in your neighborhood. I go to the AT&T website and enter my address, and it was validated. I schedule installation. I then get a voicemail late in the evening that it was canceled, after I have taken off work for the day. I call and am on the phone for over an hour and a half trying to get to the bottom of the issue. I was informed that it is a technical issue and that it has been delayed. What does delayed mean? They would have to call me when they can reschedule. Next morning from 8am to 11:30am I am on the phone with AT&T, and finally get to the solution of "We don't service your area sorry about your luck!" I asked to speak with supervisor and was told that I couldn't. Why send out personalized postcards and have a website that will allow orders to areas that are not serviceable! One of the last questions that I received was would you like to sign up on a website that will email you when there is service is in your area? Are you kidding me? The postcard and the website did nothing, why would I think an email would work? Every time I work with AT&T I receive state of the art HORRIBLE service! I get so many conflicting reasons. I started documenting all of the conversations just so that I would have references, but there isn't a customer service department that cares. There is zero accountability in the company, a great deal of passing the buck to the next department, and uninformed team members!  The Company's slogan ReThink Possible is 100% accurate, I know it is Possible but with AT&T I have to Rethink!
