This can be done by following these simple steps (https://support.xbox.com/en-US/contact-us#0:2:4):

Sign in to Xbox.com

Step 1: Scroll down and select Support at the bottom left under Xbox.
Step 2: At the bottom of the page, click Contact Us.
Step 3: Select Billing & Account, then "View Other Options"
Step 4: Select your problem
Select - "Show contact options"

I hope this helps you

I don't think you understand, I cannot get the verification code because I don't have access to the account. I input my password, it asks me to verify with the code. How am I supposed to get the code if I can't log into the account. I have no way of getting the code. As I said, the account hasn't been logged into in any other device, just my Xbox.

same deal here, tells me to update on xbox live site and it wont let me, and when i put in my pre-payed 3 month code it wont allow me to do so either. get same error code and cant access my account, so how am i supposed to update it when i cant even get
into it.

I get the error code 8015190A and my password is less then 16 digits. Two step verification is off

Hi Adam

I followed the steps and after entering in the verification code, two step authentication is still required with the second step using the auth app for the code. Again I am out of luck due to two step authentication and not having the auth app.
