Urgent : Request for refund only usage of one account.

[kukdong]

Dear Zoom Community Support.

I received a paid invoice yesterday, but I am currently only using one account for that plan.

Current Plan : Zoom One Pro (Quantity 2)

I have a questions.

1. 

Regarding the invoice number (INV255740173) paid yesterday, 
only one account was actually used. Is it possible to cancel the invoice and issue the invoice again as it was used by one account?

2. 

I am requesting to change the owner because the company has gone out of business and I do not have access to the owner's email.

Current owner account : tax @ humab.kr  (It is not using account)

Move to owner account : kukdong @ kd.co.kr (It is admin account)

 -> Owner account + Admin account is possible?

3. 

Is only automatic payment possible for credit card?
