Two for the very slow work of the sales department, more than once it happened that the offered product was no longer in stock until you receive the contract. After payment, we wait another day until the accounting department confirms the availability of money, then we arrive, wait in line and pick up the documents, if I did not have time to load the pipes on the same day, then we come again to update the documents. It feels like the factory does not know that the year is 2024 and there are a lot of process automation technologies for pennies. It takes 3 business days to purchase the product. For such a period, I order express delivery of spare parts from Moscow. It's all sad.
