It is almost impossible to get through to the departments, you have to spend a lot of time, the devices are often lost, the incorrect factory number for the devices is often put on the verification certificate, the contract states that the check is carried out within 10 working days and when you call the departments they say that according to their program they still have time, there was also a situation when When they called the department, they said that the devices were ready in a couple of days when they came to pick up the devices, they were first lost inside the department and then they put up a certificate day after day, irresponsibly doing their job.
