Hi @Bubbymunch!
Welcome to the Community Forums! I do understand how concerning it is having a different amount appear when trying to make a payment than what you originally thought was due. I can definitely help you!
Did the payment go through? If not, were you trying to make the payment through the myATT app, website, through the IVR or via Autopay?
If on the app, close the app and then power cycle your phone. If it doesn’t work afterwards the next step would be to go into Settings> Apps/Application Manager> All> MyATT> Clear Cache> Clear Data. Once done please power cycle the phone and try once more.
If you were trying to make the payment through the website, please clear the cache and cookies of your browser or try a different one to submit the payment.
If trying through the IVR, I would like to invite you to please send us a private message to @ATTMobilityCare. In the message put in your full name, account number, the best time and phone number to contact you.
If you are trying to make a payment via Autopay, it will automatically deduct the amount from the card/bank account on file. If you wish to update your Autopay information, here is a great video on how to setup/update the information.
Thank you for reaching out to us! I hope this helps and have a wonderful rest of the day!
