There are eternal queues, but this is understandable, the central bank, a large area....
I came with a question to a consultant who simply was not at his workplace (at the reception) There aren't enough employees, people are lost, they don't understand which service to choose on a computer with numbers, and I was one of them... I stood empty for 20 minutes, waiting for a consultant, and no one from the staff came up.
Good staff, courteous service, there is an information kiosk where you can put money on a card or phone without queuing, the electronic queue is very convenient, there is a queue sometimes, but not large and usually passes very quickly, so I recommend
