Where can I get help after my account is deactivated

I got error when chatting today, and got error when log in:

Account deactivated. Please contact us through our help center at help.openai.com if you need assistance. (error=account_deactivated)

The help center doesn’t provide some useful information, even not provide any email address or link to submit my feedback. So I ask here.

I have upgraded my account to PLUS, so I’m sad for this happening. 21 dollar is not a little amount for me.

Yes, I admit I use some VPN to get access to openai. But I never shared my account with others, neither ask any offensive question before. just for academy.

Thank you.

btw My deactivated account name/email is same as account of this forum, RudySusan8688@outlook.com
