I did the task, the manager on the same day (as the task was very urgent) replied that everything was OK. The next day, it turned out that the TZ was delivered incorrectly by the customer and required to perform another volume of work. The payment has not yet been received for this task, I hope for the customer's honesty, and the payment will be made in the near future.
PS
I advise the managers of the company to clearly prescribe the essence of the performance of the task in the TZ.
