My mother made a purchase with delivery via the Caspian post office. The application said that the purchase was delivered, but the cell turned out to be empty. As a result, more than a month has passed, and they are all sorting and searching, and the money for the purchase was written off. Now they are all sitting contentedly, and the pensioner's mother is left without money. So do not order with delivery via postomat, it is better to go to your home, where you can see and touch your purchase.
The billline does not catch the connection well. You have to go outside, catch the network, open the Caspian application, select the QR code in the Caspian application and quickly run to the terminal until the connection is lost.
