Hello @dataentrylady,
Thank you for reaching out to us on the Community Forums! I’m very sorry to hear a payment was taken out which you did not authorize. I will gladly assist you with this.
It is possible the account may have been setup on auto-pay. Double check your account by logging in to att.com. Go to myAT&T > Billing, Usage, Payments > Manage AutoPay.
I will also be sending you a private message shortly to gather more information. Please let us know if you have any additional questions. We are eager to help you!
Jonathan, AT&T Community Specialist
