My account disappeared?

I literally verified my email yesterday yet still can’t login with the email. It literally tells me that my account doesn’t exit. And I’m 100% sure that my email and password are right because browser automatically remembered them. This is totally unacceptable because I just bought the c++ course yesterday.
And right now I can’t even get access to the website which makes the situation worse.

And right now I’m using another account that I just registered to post this topic.

Try going through password recovery?

I did and it told me like this

seems that my account just doesn’t exist in their database=//=

It could also be the site outage going on right now…

I guess so, the seems to be down, guess I’m just gonna wait until it’s repaired. QAQ
