A terrible company, masters of boors, zero professionalism, they say the diagnosis is free, and then it turns out that it costs 5 thousand, despite the fact that the vacuum cleaner was not even disassembled. They offered to clean the dust for 25 thousand. I strongly do not recommend it.
Those are still tiny thieves - they demand money for every little thing. Supposedly free diagnostics are actually paid. They also ask for payment for the setup, although they have already taken a considerable amount for repairs. They repair for a long time and God knows what they manage to screw up while the equipment is in their possession. The workshop itself is squalid - it is located in the basement. In a word: an irresponsible company. I do not recommend it.
I brought a vacuum cleaner, which they could not repair, although they promised on the phone that there would be no problems. I spent time and money on a taxi.
