Added Money for minutes, Plan Auto Renew Didn't Work

For years I've had a Nokia Lumia 635 with $40 auto-renew plan with 500 minutes and unlimited data and text.

I ran out of talk minutes in the previous month of my plan, so I went to my online prepaid account and added $10. I did this one time before with no problems. This time, every time I made or received a call for the rest of that month, it sent me a message telling me it deducted 10 cents for every minute.

BUT this time, when my monthly plan auto-renewed Aug. 25 (which it confirmed by the usual text messages), it added $40 to my account online instead of renewing the plan, and continued taking 10 cents out every time I use talk for a minute. Online it says my plan expired Aug. 26.

I also just got a message today on the Internet Explorer app that "AT&T Free Msg: It looks like you want to use data but have none available. You may need to add a data package, refill to use pay-per-use data or change to a plan that supports data. To check your plan and manage your account, start at att.com/myprepaid. If you just made a payment for your monthly plan with data, power your device off and back on, then try again." I restarted to no avail, and also took out the battery and it didn't help.

It's like the phone/service doesn't recognize that the monthly plan renewed, and it should go back to normal instead of deducting money each time I talk. It should also give me unlimited data and text.

HELP! I don't want to have to make a long call to support and burn through the money it keeps deducting in error.
