When you opened the Atlantis account using the same credentials your details were phished and someone logged into your SR account and stole your bitcoins I'm afraid. Please change your SR pass phrase and PIN before using the account again and never use the same credentials for any of your online accounts, you are leaving yourself wide open to being scammed.
