Additional information: I have also sent my previously connected email address to the support team, which was private. I also have access to my Telegram account (@bfourw), which has been mentioned multiple times in the POA post. That can be verify from ninjastic.spac

I don’t know about normal response time from support. Still waiting for their response. Do you guys think this proof is enough to recover?
