A lot of trouble with the deadlines. The user did not understand the order.

My fault is that it was a little late. But the client Blin, a good man, himself did not claim urgency, but on the screenshot that I showed that the work was done, he misunderstood me, decided that the work was done not in that language and wrote a bad review, although he could wait an hour or another and be with the work. Now, unfortunately, show and prove nothing, because I have no motivation to do that. But the client himself does not understand anything and confuses. I don’t recommend.
