Бухучет расчеты

The executive placed a bet, I paid it and after 6 hours of work wrote that the work would cost three times more. The work had to be done in the course of the days. I offered to pay $3,500 for the card. I refused because I ordered a job for 1.5 thousand.
In the profile of the customer there are many unfulfilled work. This is such a scheme. Don’t go. You’re losing your nerves and time, and the most important thing is not getting a job.

I am in Russia, I am in Ukraine.
The stake was accidentally placed in rubles.
As soon as the reserve passed and I noticed the mistake I immediately wrote to the customer, with a proposal for a peaceful settlement of the situation, to which I received a lot of negative and inadequate reaction instead of a constructive conversation, even a negative feedback. With a predicted number of unfinished works and a scheme of alleged fraud.
It is not strictly recommended for cooperation.
