So I have been hacked I see they have changed my email and password from the pc I was logged onto

I have filled out the account recovery form and they asked for additional info but didn’t state where to send the information as the form dosent give options to do so. I have all the information to prove the account is mine I have the email receipt of purchase made on the account, my bank details, the date I made the account, when I bought the game, ip address. What more do they need I have been trying to get an actual response for weeks now but everything is automated. I really hope Microsoft takes tips from steam to improve their service.
