The executor had to add a new functionality to the open source program.

In the 30 days dedicated to the project, the executive did NOTHING and even allowed NOTHING to write until the very completion of the project.

In the last 7 days of time war began and I thought it could be considered a force majeure and from my side it would be wrong to leave a negative comment, so I turned to the arbitration to simply close the project and return the money.

But it was enough for the performers to lie that he was supposedly doing part of the work, talking about the functionality that was already implemented in the program initially.

I decided to leave a negative feedback.
