How can I refuse a refund if I just finished filming and didn't deliver the goods as agreed?

It is suggested to contact the customer first and ask him if he wants it. If not, please ask the customer to change the refund reason. Refuse if you want: negotiate with customers and deliver the goods! If you can't contact the customer, please leave the bill first, leave a message for the customer and send a message to the customer! Refuse to send it if you don't reply! You can take a screenshot in the reason for refusal: chat history, photo taking time, delivery time, etc!

So I'm not afraid! I hope this helps.
