My AT&T Prepaid account has been changed, cannot make calls. I didn't change anything. How do I fix this?

I have been to 2 AT&T stores today and they told me they could not help with accounts that have been "disconnected" and so I called support (with neverending hold times!) and they told me I need to go into a store. This is unbelievable. I don't know what to do. 

Hello, @GaryGaryGary77 we happy to provide information on setting up your prepaid account. 

Your previous account and number is not guaranteed to availability. Talk and data services will only work for AT&T Prepaid wireless phones and devices that support at least 4G LTE and HD Voice. Here’s how to upgrade an AT&T PREPAID device:

1. Visit one of our stores to get a new phone.
2. Place your SIM card into the new phone. (If your SIM card doesn’t fit, get a new SIM card kit from our store.)
3. Sign in to att.com/myprepaid.
4. Select My Device, then Update Device.
5. Follow the prompts to update your IMEI or SIM card number.

If your account is no longer available due to the May 2 shut down to 3g devices, you will need to start a new Prepaid account with the updated device.

I need my phone number. If AT&T doesn't want me as a customer, ok, but my phone number needs to come with me. And I need a refund of the rest of my prepaid balance. How can I get my number ported to another carrier? And how can I get a refund of my owed monies?

@ATTHelp Your responses are really embarrassing today. You know or should know a disconnected number can’t be ported.
