I accidentally canceled a booking when I was trying to modify, I then booked again and now have two charges on my account. When will one of the charges be refunded to my bank account?

I would recommend calling or emailing Rover. If you sent a submission for cancellation, you will need to contact Rover about the mistake.

Refunds:

If you have modified a stay for less days or cancelled your stay, you will get your refund within 2-5 business days.

Here is a link about your sitter's cancellation policy:

I would contact rover just in case to make sure that you aren't getting charged twice, or just cancel that booking all together and keep the second one.
