<prompt> Human: So over the holiday I received an email with an order confirmation from ATT my ISP, and the only one available in my area and it had a new bill amount about 5month higher.I havent ordered anything so the first thing I thought was maybe someone got a hold of my account number or personal info and changed it. I immediately logged in to check out my plan and make sure everything was in order. I had a notification that showed that ATT had upgraded my internet speed at no extra chargeObviously I was annoyed by this, so I dug a little deeper to figure out why the bill had changed. I then found this alert showing that the promotional discount for this so-called customer loyalty speed upgrade would expire in a month and my bill would go up 20 more per month. I then looked at my bill and found that they had upgraded my plan to the highest speed and most expensive plan they have without my consent under the guise of customer loyalty, and applied a 20month promotional rate for 1 month to make it look like my plan hadnt changed and the new bill was probably just some random 5 fee added on like most ISPs occasionally do. I immediately called and spoke to a rep named Jorge who stated that it was a mistake, that the change was applied automatically and it wasnt supposed to be applied to my account, but after telling him if it was automatic it needed to be addressed immediately because it was probably affecting other people, he confessed that ATT was aware of it and that they had received many calls about it. I dont for one second believe this was accidental. I believe they are doing it on purpose and hoping that many people wont notice.Make sure you watch your bills, because if this happened to me it is almost certainly happening to others. Im not sure what should be done about it if anything and I dont personally care at this point because the issue is resolved for me, but I do feel like ATT should be outed for this shady behavior and that someone should be held responsible, so I wanted to post to show everyone what happened. If this is the wrong place to post, please suggest a better sub. This was just the closest thing I could think of that applied and it could be sharedcrossposted from here.Edit: since there were a couple questions about my last login, the 2015 date is inaccurate. I usually log in from my phone but did it via my computer this time so I could make the post easier w images etc. Not sure why its showing 2015 as my last login as Im pretty sure I didnt even have ATT then lol ... anyway, heres the email I received, dated 123017, so this is definitely a current thingEdit 2: Since this is getting a good amount of attention, if this happens to you heres what I did: You should immediately pause your autopay if you have it so the bill doesnt get paid note that I got this email 123017, two days before the bill was due on 1118, so they definitely tried to sneak it by me. Then call them and they should credit your current bill back to your normal rate, you should pay that months bill manually, then let autopay resume. As others have noted in the comments ALWAYS WATCH YOUR BILL CLOSELY!Edit 3: Fixed some formatting stuffEdit 4: Holy moly this thread has picked up some steam! Thanks anonymous Reddit friend for popping my golden cherry!One last edit: from a PM I received...the sender wanted to remain anonymous but I thought this was great info: I work in big telcom. What you experienced is called a slam sale in the industry. Its when a salesman places an order for you, without ever receiving your approval for the order. The salesman gets credit for the sale, meets quota or receives a big bonus. Oddly enough, this is not a very common tactic today. It was popular until 10 years ago, and its almost unheard of today. I wasnt aware that ATT was experiencing Slam Sales today. You can protect your account from Slam Sales. All the major telco providers will offer authentication-secure account protection. Call ATT, ask for billing, and tell the rep that you want to password-protect your account from unauthorized sales. You can setup either a password or a PIN that must be entered to make any account changes. Sorry this happened to you.And another PM:I also work for a major telco as wellname is somewhat synonymous with dicks, the account PINPassword is visible to us when we do verification and would not stop someone from putting sales on random accounts. Pretty much every ISP and cable company uses outdated billing software from the 80s thats a glorified AS400 mainframe running with a 90s era gui overlay. Scroll about halfway down in this pdf for some screenshots.  <response>: I just want to personally thank you for outing them. Consumers should do this as much as possible on sites just like these because basically ATT was attempting to STEAL money from you. I dont care if they arent breaking into your home or robbing you at gun point, this is theft. I wish I could give you more than one upvote.
