I was charged twice for a 1x walk i ordered with a sitter, how do i get refunded?

I suggest you call Rover Support [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]

Sometimes a duplicate booking in error happens. Rover can refund it. I'd suggest the quickest way is if you let the dog walker know of the duplicate charge and ask them to have Rover support refund it. It will take 2-3 business days after that.
