Super confused — account deactivation?? No customer service

I’m already noting from the previous posts about how bad the platform is in terms of seller customer service. But, I’m not seeing information anywhere about how to get into contact with one of these guys to help me with my account. My account has been deactivated for 2 months and it seems like there’s a billion glitches on their end so it’s extremely difficult to fix. How do you guys even contact anyone??? Even email or form would suffice. What tools do you guys use? I even contacted amazon -regular side and they said they had no idea how to contact anyone in seller central.
