Can't log into my D2 LoD account

I’m trying to log into my D2 LoD account, but the game keeps insisting that my password is wrong. I’ve tried every password that I’ve ever used, but nothing is working. Very weird since not too long ago my password and stuff was saved in the game and I didn’t have to type anything. It also seems that any type of account recovery option does nothing.

Can someone help?

Looking into this no D2 account was able to be found from the current information available.

As this may require sensitive information for account recovery you would need to contact Customer Support directly.

It should be possible to help find the account and recover it hopefully.
