I finished a rather lengthy job last week, and now, on the 5th day since I submitted it, the customer has returned it for corrections, citing "- The translation contains spelling or grammatical errors. - The translation misses key meaning or details from the original."
But the comment they provided doesn't specify anything. Instead, they ask if it is possible to send a Word format document with comments for me to respond to (without uploading any new files). It's night in Japan right now, and my corrections period expires in 20 hours. I don't want to lose the job without having had a chance to correct it, and I also don't want to send back the same thing just so that I can beat the deadline. What should I do?
