my xbox account was hacked and the hacker changed the email and password

Password the same as other passwords? Dude, that's like wearing a HACK ME sign at a Hacker's convention. PLEASE make sure the password is different on the Xbox service, as hackers who get into an email account using the same password now have your Xbox password.

the hacked manage to delete the email i use for that microsoft account and changed his/her email as primary email,
and also hacker manage to remove my phone number from the account also.

so how can i prove its my account when hacker manage to delete my email use for the microsoft account and change all the my profile info??

When I go on there my issue isn't available to report and when I put in that I've been hacked and the hacker changed my email It says calls arnt available for issues and it tells me to change my password when I cant

If there is still a phone or alternate email address to the old account (which the hacker probably just changed the email address, and not deleted it), then you might be able to recover it. But if the hacker already changed the alternate email address or phone from the hacked account, than nothing can be done.

Mine got "Fifa hacked" a few weeks ago, gave support a ring and within 2 days I had received my MS points back and all seems to be secure now.

Change your password ASAP and I'd also recommend changing your EA account if you have one as I believe thats how the hackers get in, also make sure your password for other gaming accounts are changed as the hackers also got into
my blizzard account, they even had the nerve to send an email to blizzard support asking to wipe my account, also is sorted...for now.

-Give support a ring and change any passwords to any accounts that you think could be compromised.
