Mediocre service (particularly for elderly customers).
Delete 5 files - 5 rubles, download the app from the Play Market - 5 rubles. The management should do some work and stop trying to extort money from customers.
According to the classics, the review is unlikely to change anything, but suddenly.....
In the summer, I applied to put the tariff on pause. The girl called someone and tried to do something. As a result, she said that the phone was on "pause". After a couple of months, it turned out that it wasn't. There was no way to put on a "pause" via SMS, the sim card went abroad. In general, the staff is not competent.
