No one is immune to aggressive customers. Although this man is my countryman who moved to another country. And got the job he ordered. But alas, he decided to just ruin my reputation and put such a rating.
I, too, first thought that I have no orders from the review but in fact there are 250 other positive reviews from other customers. And many know that I have high-quality service, but still no orders. Only sometimes come my regular customers for new orders.
How to act in such situations I do not know. But in my opinion one unfair review should not affect the total lack of orders.
