Billing Error (No invoice attached for unknown transaction)

[Farahly]

Hello, has anyone experienced being charged money on your credit card, and the email confirmation of the order doesn't have any invoice copy attached to it? We are not aware of why are we being charged. Reached out to billing support and they said that it was credited back to your account which we can use on the next Zoom transaction but there is no email about it that we can use as reference. We also had a pending ticket about our account having reached a 95% limit when all our calling plan is unlimited. None of the support I chat with can tell us the reason behind it. I tried calling Zoom phone number and no one is answering.
