Incompetents and arrogant. I don't recommend it. There is no service center in Grodno as such. They attract third-party craftsmen. Installers smoke a lot and obscenities.
Manager Sergey just killed the price - he ordered it a week later. They explained everything on the phone, how / what / why/Whatever's best. On payment, Sergey also told me how best and what they can offer - I was more than satisfied. Pavel came to the measurement (but I may be mistaken) an adequate guy, told me everything where everything needed to be corrected, agreed on everything. Ultimately, the company is right TOP!
