They called several times, in response they turned on a loud alarm, either the problem was in the work phones, or the people working there did it on purpose.
This is the worst PSC I've ever applied to. Employees do not behave professionally, they do not know what documents need to be collected for the service, they are constantly rude, they swear with people.
Contacting this PSC is a waste of time and nerves. It is better to drive to the nearest PSC in Karaganda.
