How do I cancel or change a trip?
You ask in the conversation, and you see the cost before you confirm.
You ask to cancel or change the trip in the conversation. Before anything moves, REDUVO tells you what it costs and what you get back. You confirm after that — nothing is cancelled behind your back.
As long as the free cancellation deadline has not passed, cancelling costs nothing. REDUVO warns you before that date, so nobody finds out too late.
