My experience with AT&T is one of the worst encounters I've had when dealing with a service provider.
I have their 1.5mbps dsl service at work which is something that I use for light browsing for making online orders and for entertainment. For a few months I noticed that my bill was around $40 higher, but I just thought it was from long distance and didn't pay much attention. Then I started to get calls from AT&T.

ATT: "Hello, would you like to upgrade your service to 6.0mbps free for charge for the next 3 months?"
ME: "No thank you"
ATT: "6.0mbps can do wonders for your business"
ME: "No thank you, I'm sorry but I'm busy right now, have a nice day!"
ATT: "Sir could you verify one more time that you do want the upgrad..."
*CLICK* (I hang up)

They called my business literally twice a day for 2 weeks and the calls got more and more annoying and aggressive to the point where I stopped being polite.

Then I got an email...

ATT: This is your confirmation email stating that you have upgraded to the 6.0mbps service. Blah blah blah...
(Then in fine print: "regular charges do apply when the promotional 3 months have passed please call customer service if you wish to opt out of our promotion)

I look at my old bills to make sure they didn't pull other bullshit tricks out of their asses, and I notice why my bill was higher the past few months. They had upgraded me to 3.0 from 1.5 without my consent nor any notifications. I called them to confront this and the first representative was very polite.

REP1: "I'm seeing that the upgrade to the 3.0 happened back in August, I apologize about that sir, let me transfer you to our dsl department and they'll adjust your account and refund the overcharges"

ME: "Thank you very much, I appreciate it."

REP2: "Hello, blah blah blah, how can I help you? Oh, I need to transfer you to *inaudible*

REP3: "Hello, how can I assist you?"

ME: "My internet service was upgraded without my consent, and I've been billed for it"

REP3: "Sir you are not being billed for the 6.0"

ME: "Yes, but my service was upgraded from 1.5 to 3.0"

REP3: "No, you have always been on the 3.0"

ME: "No, I've been on 1.5 since forever"

REP3: "I'm not seeing it"

ME: "Can I talk to your supervisor?"

*CLICK* I get hung up on...

Their customer service is abysmal and they will do sneaky things to steal money from you.
You should stay away from signing a contract with them if possible.

By the way, I've done speed tests multiple times after I got my 6.0 "free upgrade" and my download speed has never exceeded 2.0mbps... which is the same as when I was using my 1.5...

Yeah AT&T is a sham

AT&T Service Sucks and this is in plain English!.
Another company needs to come in and replace them; we need more choices as consumers in who we want service from, in Orlando Fl. the only company that we can get phone service from is AT & T, we don’t have a choice to change other companies are not in our “Area” Who decided this???... Why should we have to continue to deal with a company who does not take pride in delivering the best service?
We need more choices… Why keep a business in business is they are not doing their jobs, it’s us who pays their salaries; it’s us who keep them on top. Wake up Americans….

I can't stand AT&T commercials with their "minutes". Especially the mother and son commercial, it's like they're staring at each other for a few seconds before the commercial ends and there are other commercials like that too. Whenever I see it, I just flip or turn away from the screen. It's really that annoying. Stop!

Several months ago a salesman came to our door. We politely said, "no thank you" after explaining to him we were already happy with the services we have contracted. He returned the next day. Apparently he did not take our answer for face value. Understandable, since sales are important. We politely said no again. He left. No problem.

A few days ago, another sales person returned to our house. My husband talked with her explaining that we were again happy with our current services and that we were not interested. She pushed a little harder but eventually left.

Today another saleswoman came to our door. I said no thank you. She left. Not one hour later she came back. I chose to ignore the door bell. She continued to ring the bell and actually yelled through my window for me to come talk to her.

I would appreciate it if they could stop sending sales people to our home. It has become harassing now. We have been clear with our answer. No Thank you. We are already phone service customers of theirs and it was over the top rude how we were treated.

Last month my phone stopped working out of the blue. The phone company sent someone out and said it came from the inside. On our phone bill they charged us $85.00 for them to trouble shoot. When did it become a standard to charge someone for looking into the problem up front? It used to be part of the service you had for paying the monthly bill. With this kind of service I might as well cancel my house phone and maintain my Verizon cell phone as the sole phone. At least they know how to work with their customers!!! Where did the friendly BellSouth company go...
