@karan2 Unfortunately there is no “urgent support”, you just need to wait.
The only way to contact the correct team is what I’ve already provided.
If you have filled out that form, then you just need to wait.
Regarding your Page not found issue…
I’m not sure how you have a Netlify site deployed if your account has been blocked.
Creating multiple accounts is one signal that will make their automated systems block you.
The relevant Support Guide is here:
