If you have a personal account:
Log in to your personal account and go to the «Support» page. Then create a new ticket. You will be asked to specify the topic and category.
If you do not have a personal account yet or you have lost access to it:
Go to the «Support» page. Then create a new extension without logging in to the site. You will be asked to specify the topic and category. The answer will be sent to your email. This method is designed so that users can contact support without logging into their personal account – for example, if you have lost access to your personal account and want to restore it.
Please visit the “Site Features” page before contacting support. It contains all the information about the work of the site, subscription, lessons, personal account and other sections of the site.
