I was putting up a window. So at first they made a mistake with the measurement and brought a window that was not suitable in size. We pulled on the film and went to swim, it was in the month of November when the frosts and the apartment were frozen. Then they brought it without a net. When paying, she said that the mosquito net had not been brought. So they drove. Then, when we rushed to install it in the summer, but it does not fit in size. So I had to buy a grid from another company. That's the kind of company.
