1️⃣ Call Xbox Support Line which is +1800-469-9269. Start by saying you're trying to recover your gamertag from xbox live and you don't exactly remember your email but you remember the info. Give them a fake name and the Gamertag you're trying to jack. Once they have the account pulled up say you were on hold for awhile and your phone is about to die and that you need a reference number. Make sure the account is attached to the reference number, Tell them to attach the contact details to the account so when you call back they can pull the info up right away.
2️⃣ Then call +1866-663-2273 which is the number for OneCare(A service line provided by Microsoft) Or 1866-727-2338(PC Share which is a service line also offered by Microsoft(prefer you call this number though) Give them the reference number you got from xbox support. They may not give out the info everytime but call until you get it. If you call PC Safety, punch 1 multiple times till you get an operator. Once you're on the phone with an agent give them the REF # you got from xbox and they will most of the time give you the info without asking. If they don't give you the info say "Can you please verify me my info?" If they don't, hang up and retry till you get it. Just keep trying till you get it.
3️⃣ https://windowslivehelp.com/PasswordReset.aspx is the site you will be going to put in the info you got from the support line for the email that they provided you thats linked to the account you are trying to jack. and fill out the questions with the info you got from either of those Onecare numbers. Fill out the questions accurately as possible. Answer the question where it asks for your IP which you can find out by going to Ipchicken.com and ISP like roadrunner, etc. There will be questions like "Names of contacts in your Hotmail address book" there, put YOUR email. And other questions like "Subjects of any old mail that is in your Hotmail Inbox or mail folders" there, put Hey man! And 2 more questions that ask "Names of contacts on your Messenger contact list" there again, put your email. And a last question that asks "Your Messenger nickname" and there, put the name of the person who is linked to the account.
4️⃣ Leave all the questions you cannot answer blank. At the bottom there will be a question that asks "Name as it appears on the credit card used for services" Put the name of the person you are hacking, even though they may not have a credit card on their account. After that put this comment in the comment box at the very bottom, Sorry I couldn't provide the last 4 digits of the credit card number. I used a visa gift card to buy a subscription card. After I purchased the subscription expired I threw away my card because there was no money left on it. I really need my email back because it is linked to my paypal and bank information. And also make it sound as drastic as possible.
5️⃣ Once all these steps are done, click submit. Then go to your email and compose a email to the person you are hacking. Put the subject as "Hey man!" without the quotations. And put whatever message you want. Also Make sure it makes sense, So it will be alot easier to attack and retrieve there live account.
