I tried the "forgot password" option. Unfortunately, it does not send a password change e-mail.
It is the exact same case that has already pointed out by M.zahra on July 28.
Accounts with relevant pending payouts are mysteriously deactivated after years of functioning.
Strange.
Well for their email service, I think it's going through technical issues as they haven't send any promotional email since July 27 th.
But for the wrong credentials, I'm not quite sure.
Hope it will be fixed soon
