I used the services of the company. The result was quite satisfactory - I submitted my diploma. All revisions were done for free. However, I want to add a "spoonful of tar" - there is a 3% commission when topping up. I understand that this is charged by the payment service, but it’s still unpleasant. I want to express my special thanks for preparing the report for the defense (I received it as a bonus). We managed to stay on schedule, but it was really tight; the work took about a month.
