Unfortunately, all the positive interest in classes disappeared at the stage of communication in Yandex.direct. An incomprehensible negative in response.
1. Complete disinterest in the client.
2. Very long and incomplete answers.
3. There is no trial session.
4. Politeness in communication is simply zero.
5. The manager gives strange answers instead of trying to figure out the situation. It seems that she also answered in Yandex.Direct.
