i do not have twitter should i have to connect with them?
This is not serious.
I will try
If you have no twitter account then you can contact them by sending personal message to one of these accounts
JETWIN_SB or
BOOKMAKER. Indeed users of Jetwin is not really secure as there is no option to reset password as well as 2FA. As I remember the 2FA was planned to be added last month but it seems it is not yet available unless I miss it.
Two Factor Auth (2FA) is available under SECURITY tab in MY ACCOUNT section.
