I have a recent experience on Fiverr order cancellation.
I have worked with the buyer on Api integration and got payment after delivery. After 3 months they said I deliver them partial work and they need 50% refund. Those are the new features so I explain to them and suggest days and budget for a custom offer but the CS has canceled the 3-month-old order very next day and the funds have been returned to the buyer?
I opened a ticket but I did not get any response for 24 days.
Is this possible for every order to cancel after some time when it has been delivered a long time ago?
