Orders cannot be cancelled once shipped. If you would like to cancel your order before it ships, there is a 10% restocking fee deducted from your funds.
We are unable to change your payment method for you. You can call us to refund your purchase on your purchase on your payment method, but your items will be released and likely go to someone's elses waitlist.
Unfortunately, we can't. The only way we can do that is to cancel your order, and most likely your items will go to someone else's wait list.
