The balance runs out, but you won't find out about it. You won't receive a notification, and there won't be an invoice either. When you log into your personal account, you'll be scratching your head, but you still won't understand how to generate a payment invoice. You might try to write to customer support, but you won't get a response. You can't reach your personal manager either. If you write through the application form for connection, they'll call you back right away. You'll tell them to ask the personal manager to contact you, and he will call, but only after a few days. You'll ask him to send the invoice, but in the end, you still won't receive it... And the phone number listed in official sources goes silent for an indefinite period. Well done, guys!
