My partner’s account has been blocked after being hacked.

The system you have does not allow us to set-up SMS recovery - only to use an old, out-of-date & closed email account.  We are now unable to re-set or access the hotmail account. We have tried all the links & options, but keep getting back to the same sign-in page to a blocked account to access any info(!), & the old closed email account to receive a code! We are going round in circles at every turn!!!! What can we do now???
