My client was not online so my order got completed automatically. I missed the review and rating. Now client is online and asking me to make little bit changes to the design . Is this possible , he can give me review and rating now?
Your client has 10 days to leave a review after the order was marked as complete.
Also, if they haven’t used up all of their revisions, and you refuse to modify the work, they can complain to Customer Support, and CS will side with them.
I do hope you don’t plan to ask them for a rating, or even mention it to them.
