Hi Chad,
You may want to contact Rover support at 1-[Edit: Rover’s contact options have changed. Visit the Rover Help Center at https://support.rover.com/ to find the phone number, help articles, or chat with the team].
Payment is processed when the stay is booked and shows as a Rover balance until after the stay ends. Then, the sitter can then choose to receive a check, redeem it through PayPal, or use in the form of Rover Bucks when a sitter is needed for their own pets.
Since you didn't book a stay, is it possible you placed an order for items at the Rover store?
