Urgent: Locked out of 30-year Hotmail account due to international relocation

Hello. I am completely locked out of my primary Hotmail account (which I have owned for nearly 30 years) after relocating from Sweden to Tunisia. I know my correct password, but Microsoft is blocking the login due to 'unusual activity' from my new country, demanding a verification code sent to an expired Swedish phone number. The automated ACSR recovery form keeps rejecting my requests despite me providing exact historical sent email subjects, likely due to the geo-location conflict. I am posting from a temporary Outlook account because the main support page is stuck in a loop. Can a Microsoft technician or moderator please escalate my case to the Account Reinstatement Team or provide a direct channel to human support?. The account profile displays the initials 'MH' for Mario Hicheri, which matches my recovery Gmail address. I may have registered it under this nickname when I created it 25-30 years ago in Sweden.
