Account apparently cancelled after having repair appointment set up.

I'm a new ATT Access customer. I received my Wireless Gateway in the mail for a self-install on the 22nd. However, I did not receive any broadband signal (red blinking light on my gateway) after the self-install date and time (2/22 after 2pm). I called customer service and was told to wait until 5pm--then 8pm, but there was no change. I spoke to customer service again after 8pm that night and an installation appointment was scheduled for the next day for an 11am-1pm window.

On 2/23, no one showed up. I called customer service for the THIRD time and was told that the appointment was for the technician to check the outside of the building to see if everything was hooked up correctly (even though I was told by the customer service agent I spoke to the night before that they were going to install it in my apartment + I had to be home at that time). She then told me that there had to be 'something wrong with my phone jack' and she was going to send a repair technician to my apartment and set up the appointment for 2/25 with a 8:30-9:30am window.

I was fine with that until I received an e-mail from ATT this afternoon stating that I had cancelled my account on the 23rd and needed to return my equipment. WHAT? I didn't cancel anything! It shows that I cancelled my account on My ATT as well. I just got off the phone with customer service and they apparently can't access my account and transferred me to the cancellation department (which was closed--why send me to a closed department???). They also said that they can't see any appointment listed (if they can't access my account--how could they see if I have any appointments listed?) However, I get a message that a repair appointment is scheduled for tomorrow when I initially call (from the automated voice), so I do hope someone shows up.

I'm at wit's end here. I just want my internet installed and/or repaired am tired of the  B S ATT Customer Service is peddling.
