Well, that's a pain!
We can totally help you out, and the first step is to understand what the issue is with the help of our support team.
Please get in touch with our support team (in the app or via email at firstname.lastname@example.org) who can investigate the matter internally.
It's also very helpful if you can include information on the transaction that's wrong: any information on the amount, the purchase method, etc. would help. If you have a screenshot of your current budget or booking history, this would equally help the support team with your issues. We'll fix it! 💪
