Billed twice for one license

So our client  change her domain.

And it will change email too.

At the same time her zoom license has expired.

We pay her license and then change her email account.

And we realized her zoom license still expired.

We though the first payment was failed.

We pay again and that how we got billed twice.

Lesson learned, do not change your email address.

Make a new zoom account.

They suck at this.

Thank you
