Cancel buyer's order without losing the rate

[Guest rakibhossan]

I have received one order from my buyer. its duration is 30 days. now it passed 19 days but I want to cancel this order without increasing my order cancellation rate. How can I do this?

You can’t. Any cancellation will affect your completion rate.

Then, How can I recover it?
