Business Account Sign-up Loop?

I've had a business account with AT&T for a few years now and I've never been able to sign into my online account. I pay my bill without signing in.

Every time I try to register my online account, I'm sent in a loop between "AT&T Premier" and "myAT&T for Business". Here's the loop in detail:

1. I go to myAT&T and click sign in.

2. I click "Don't have a user ID? Create one now".

3. I select the option for "Wireless" and I'm asked for my phone number and billing ZIP.

4. The page displays an error message... "To register your small business account, go to Premier."

5. Now on the Premier website, I click "Log in".

6. I click "New to Premier? Register now".

7. I select the option for "Administrator" and I'm asked for my email, phone number, and FAN PIN (which I do have).

8. The form is submitted and I get an email which says...

"We received your request to register for a Premier profile. We've moved small business management to myAT&T for Business, which is designed for businesses like yours.

To manage a wireless account, create your myAT&T user ID. Don't forget to bookmark the page for future reference."

This puts me right back at the first step of the loop! I can do this over and over again.

How the heck am I supposed to register for an online account?

By the way, I've tried calling the support number. I was passed around to other support people and was ultimately unable to solve this problem. I even tried going to my local AT&T store where I was told that they couldn't do anything about it and I needed to call support. So now I'm here in this forum desperately looking for help.

Thank you for any help you can give me,
