How do I get my Microsoft account back after it getting hacked?

Hello Microsoft Community,

I'm reaching out for urgent help with my hacked Microsoft account. Despite my best efforts, I haven't been able to regain access to my account and am feeling quite frustrated and helpless.

Here's a summary of the steps I've taken so far: I first noticed unusual activity on my account and realized it had been hacked. I tried contacting Microsoft Support through email and phone but did not receive a resolution. The phone calls only connected me to bots, and there was no option to speak with an actual person. I meticulously filled out the account recovery form, providing every detail requested. Unfortunately, the response stated that I didn't provide enough proof, even though I included all the information asked for in the form.

I wanted to include some details of my own, like screenshots proving my ownership and showing that I have had access to it for many years. Additionally, I have previous communications, purchase receipts, and other relevant data that could help verify my identity. However, the recovery form did not allow for this.

I'm feeling quite frustrated as this account is crucial for me, and I am at a loss on how to proceed further.

As a last resort, I am considering contacting the police and the GDPR authorities to request Microsoft to delete all my information and permanently delete the account to prevent any misuse of my data.

Could someone from the community or a Microsoft representative guide me on what further steps I can take? Are there any alternative methods or additional support channels that might be more effective?

Thank you in advance for any help or advice you can provide.
