VRBO Technical Question about Stolen Credit Card

[Jen Faulkner]

I have a guest who will stay at one of our properties in September.  He paid the first half in May when he reserved the dates.  He told me today that the debit card he used has been stolen/hacked, so he canceled it, and he asked to make his second payment with another card, which is fine.  However, my question is what happens to the payment from his first card since I haven't received the payment yet?  Anyone who uses VRBO knows that the guest gets charged up front, but the owner doesn't get paid until after the guest leaves.  Is it safe to assume that the card has already been charged, and the funds will still make it to my bank account?
