AT&T bill paid but I still have the money?

Since you've checked your account and have proof that they haven't taken it out yet, call them and ask about it. Some businesses are very slow about this, so it's best to confirm that they will be debiting it. And ask when, so you don't overdraw. I've had to deal with two entities that hold onto debits for up to a month and only push them through when they get around to it. Better safe than sorry.

Check with your bank to see if there is an issue. Don't spend the money. Eventually, it will be taken from your bank account. Could be a system glitch or holiday slow down.

Be a little patient and when you least expect it, it will come out.
