Withdraw money back from account

We are working on a project with different members, if I add some money as balance, later we want to discontinue, can we withdraw our money back?

Refer image, I am talking about money/credit we add:

Money goes in. It is instantly converted to something valueless. It doesn’t come back out. It expires. Your numbers in a database can be cancelled unilaterally. Per terms.

Despite that a monetary credit balance doesn’t present that way at all to users or in use, and is administered as money by a merchant payment service’s billings.
