How to make a form in Steam Support

Hello! My account was hacked.
Here is my login from the stolen account (login), the approximate password from which you logged into the account (password)
I do not remember my mail that was linked to the stolen account.
Steam support answered me a day later!

It may also be necessary to provide confirmation of purchases to them

"Hello, I lost access to my account (login), (you can write the password that you remember). It was tied to the mail (mail.), To the mobile phone (number) (if not tied, then do not write. I put on it money / paid for purchases from webmoney / qiwi / credit card / from the payment terminal / from something else. (of course, you need to indicate the account number and attach screenshots or other proofs. the game, which is written on a piece of paper and tied to the account).
Like everything. And for the future, connect a mobile authenticator (of course, this is not very convenient, but the account will not stand)
