the bill way over charge

If you are on automatic bill pay, then they did have authorization. The amount of the bill changing doesn't mean they have to get separate authorization.

Now why the bill was different is such a big amount is the question. When you read your bill and compared it to the normal one, where was the difference? Any new charges? Existing charge in a different amount? Any credits drop off?

no its not on automatic bill pay my monthly bill $12.85 for the past two years, that low income , and now i received a new bill $47.45, what is going on att just trowing numbers no base for it. att give me credit for the $72.26 than later removed something wrong with the billing dept.

The only way AT&T would take payment is if you were set on auto bill pay, you closed your account and left an outstanding balance, or a one-time payment was submitted. Since you say it was not authorized, and assuming your account has been active, I would check to make sure your account wasn't put on auto bill pay.

Instead of just throwing the number, what are the itemized details of each bill? That should explain where and why the difference is. That way you have knowledge on what to dispute if an error or what else needs to be addressed. Otherwise you would need to call AT&T to go over the bills in detail to find out what happened.

When i call att i wait over 40 minute then a women answer and her voice was dead and very helpless, all what i want to know where att get this monthy bill from $12.85 jump to 72.26 then to 47.45.

Did you do recertification for the ATT ACCESS account?

If you do not submit the application with documentation to recertify then you lose the $10 per month status and would be placed in a same plan at normal rates which $72.26 sounds correct if $60 internet plus $10 gateway fee for $70 plus fees of $2.26

If approved if ACP that has a $30 discount per month (60-30=30) plus equipment fee plus any additional line items.

The details are on your monthly billing statement, have you compared line by line the last three months billings?
