Can I cancel something I said I would give?

Yes, as long as it has not been confirmed as delivered. On your dashboard, next to it, tap "This isn't available anymore", write one honest line about why, and tap Confirm cancellation. The organisation sees your reason straight away, so they can look elsewhere. Once help is confirmed as delivered it is a permanent record and cannot be cancelled. Money already paid has already reached the organisation and is not refunded by cancelling.

This one applies to: I want to help.
