U-Verse TV Disconnection

Yesterday I called ATT to discuss my options for reducing the cost of my U-verse TV.  I was offered DirectTV as an option and I let the customer service rep convince me that it was a good option and agreed to switch to DirectTV.  I was assured several times that my U-verse TV would not be interrupted or discontinued until my DirectTV was installed (which would be 2 days later).  I was also informed that I would receive an e-mail confirmation of the changes that had been made (I still have not received any e-mail confirmation).  As soon as I hung up the phone, my U-verse had been disconnected.  I called ATT and spoke to a service rep in San Diego (I live in Georgia) and explained everything to her and was told that the U-verse TV had been disconnected by mistake because the first date that comes up for disconnection is the current date and the rep hit that button not realizing that she was disconnecting the U-verse service immediately, and also informed me that once the button has been pushed, it can not be stopped.  That was not a satisfactory answer to me so she spoke to her manager and they had other conversations with other managers and then I was  told they would work on getting the U-verse service reinstalled but it might take 24 hours and someone would call me.  So after spending 2 hours on the phone with ATT yesterday, 24 hours later I still have no TV and no phone call from ATT.  I called again this morning and told my story to a rep in the Phillipines who transferred me to another rep (also in a foreign city) and was finally told again that once the U-verse service is cancelled, there is nothing they can do except have me talk to someone in sales and re-order U-verse, but he suggested that I just wait until tomorrow for the DirectTV to be installed.  (I worked in customer service for 22 years and would never have gotten away with that kind of suggestion with my customers.)  I had him transfer me to sales and got another rep in Southeast Asia and told her my story and she finally came back and started to tell me what she had found out and she disconnected us!  She did not call me back and, of course, I would never have been able to reach her again because she was in Southeast Asia!  After spending approximatey 3-1/2 hours on the phone with ATT reps over the last 24 hours, and asking to talk to a supervisor or manager (which I never had the opportunity to do), I still have no TV and no answer!  After 40+ years with ATT, I'm ready at this point to cancel my other services with ATT (internet and phone) and go with another provider.  I can't believe the lack of satisfactory customer service support I have received from ATT over the last 2 days.  The rep that disconnected my TV probably doesn't even know that she did it and apparently ATT doesn't care.  If you can disconnect a service with one push of a button, why can't you reconnect it the same way?  And why can't a customer reach a manager instead of being transferred to different reps all over the world?
