Just one phone call to the Kiev office of this company forced me to post this review here and in other places available to me. When choosing a supplier for my company, I called the manager (as I understood it), whose name remained unknown to me, with questions about the position I was interested in. I did not pay attention to the answers that were given to me with irritation, since we are all human beings, but to the elementary question of whether the sleeve is reinforced or not - I was recommended to "read GOST standards in which everything is written" so as not to ask such questions. I explained that I was not an expert in this matter and that's why I called to get a consultation. After all, this is the job of a manager. To which I was answered: "Did you call to show off or talk technically competently?" (a literal quote from the manager). I thanked him for his help and hung up. From this conversation, I conclude that perhaps "technically literate" people work in this company, but they are definitely boors. I will dissuade all my partners and clients from working with this company
