I seem to have been maliciously ordered. A customer has purchased a large number of large-sized goods many times, and the amount is large. However, the Canada Post is on strike and the customer's area cannot be delivered. We contacted the customer to cancel the order, but the customer did not respond. In order not to affect the late delivery rate, we cancelled the order for the customer, but the customer placed a large number of orders again, and the message was not responded. The three order numbers are 701-6012541-2754602 701-0878326-9678629 701-6577376-3908239. Now our pre-delivery cancellation rate is too high, and the appeal is unsuccessful. What should I do?
