My CC # changed - now my entire Adobe Account Changed

My personal CC # changed.

I updated it in your system on November 30th.

I have five notices now of failed payments.

The payment is in "preauthorization" mode with my bank - the hold expires on Friday.

Now, when I log into my Adobe account, there are no orders, no invoices, no activated devices.

I have already made four payments.

It looks like you placed my account into an "Enterprise Plan."

I'm just a teacher with one account. We don't use an Enterprise Plan in our school district.

Please advise ASAP. Thanks!
