Moreover, they work in frosts day and night, on weekends and holidays... Many thanks to the staff (in particular Yuri and Sergey) for solving the problems quickly. The choice of an organization for the maintenance of the next boiler was decided by itself, THANK YOU VERY MUCH!
Maintenance is OK, but the dispatcher accepting the order, 6.10.20 at 8.50, was very rude, after which there was no desire to contact this organization at all.
