Account keeps getting locked?

Just for safety, i'd recommend putting 2 step verification on your account.

Same for the past week ive been getting locked 2-3 times a day

I live in the US and qualified for that bundle, the Discord nitro code was just bad and microsoft needed to give me a new one (Discord told me it was a bad code and to have them make a new one) and microsoft just had 0 idea how any of this worked.

I'd check the sign-in activity on your account to make sure someone isn't trying to sign in with wrong credentials as I believe a certain number of unsuccessful attempts results in an account lock.

Go to you Microsoft account (click your avatar top right of the screen then select "My Microsoft account")...from there, click on "Security" and there should be a "See your sign-in activity" option.. Click that and it will list every successful and unsuccessful sign-in attempt

if you ever have that problem again. You can use a VPN, which changes your ip address to a country of your choice. This would enable you to activate the offer
