on Cortex telegram group they when you send 5 eth they will send you back 10 eth I speak with admin and he told me that I need to send more and mroe and more then he blocked me so d ont deal with this shit stay far
i think you just got scammed from the clone because if someone talks to you with the admin title first usually it's a scam
because IMO there is always notice for every project that Admin will never PM you first
