On 03/02/2026, we contacted the company about periodic failures and Internet outages at 3 Golodeda Passage. The customer service responded very promptly — on the same day, Igor Osmolovsky, a service engineer, came to us for diagnostics. Igor promptly found the cause of the problem and fixed it pretty quickly. He worked confidently and calmly, explained everything in clear language. In communication, he is a polite and pleasant person. Now the Internet is running smoothly, just flying) We are grateful to the company for its prompt and high—quality work, and to Igor, the specialist, for his professionalism!

I am very pleased with the work of master Oleg Evgenievich! I arrived on time, did everything quickly, accurately and really efficiently — the Internet started working without any problems immediately after setting up. It is clear that the person is well versed in his business. I would like to mention the pleasant communication separately — I explained everything in simple and understandable language, answered questions and created a very comfortable atmosphere. Such specialists are rare: professionally, promptly and humanly pleasant. I definitely recommend it!

I would like to thank Sergey, a specialist from Kosmos, who responded to the call at 19.12.25 Tikotsky Street. I consider him a master of his craft. He works quickly, clearly, and fixed problems that I didn't even know about, even though other employees of the company came before him to work out the call.(about nothing). I am very pleased with his professionalism, meticulousness in the matter, and speed! I ask the management to reward the master with a prize, and wish to cherish and appreciate such specialists! Thanks! Good health to all!
