I cannot perform account recovery for you, but here is the official, secure process.
On 360 Dashboard: Social → Sign In → Download Profile. Enter email/password. If "Profile corrupted", delete local profile (Settings → System → Storage → Hard Drive → Profiles → Delete Profile Only) then re-download.
Contact Xbox Support (Chat / Callback) via support.xbox.com/contact-us. Have ready: Console Serial Number (Settings → System → Console Info), Billing History (last 4 digits of card), Gamertag, approximate creation date.
