I don’t understand this as well. And I am afraid these buyers can go crazy right after the delivery. You know - being silent for days and after ignoring all the drafts and works in progress, not controlling the work I do, they will leave bad review or even try to cancel the order they didn’t care about at all.
As for CS (omg, they are so fast now!):
Thanks for bringing this to our attention.
I will send the message to the buyers related to these orders, but I can’t guarantee they will respond.
Alternatives for this would be either for you to send the request for the extension of the delivery date or cancelation via Resolution Center.
If you are no willing to work with them any longer, we can review the order for a cancelation from our end as well.
I’ll let you know if they respond.
Hope to hear from CS or the buyers soon.
