Can't recover my (possibly) hacked hotmail account

Hi,

I've searched over and over for an answer or potential support service to help recover my hotmail account I believe must have been hacked. Hopefully somebody can help me!

I've had my account for about 15 years, I stopped using it for work for a few years (embarrassing teenage email name!) but when I tried to log in it says something along the lines of 'it looks like somebody else is using it'.

- I can't recover via phone as its an old number I can no longer access
- I've entered security question, name, DOB, old passwords etc. all correctly
- Entered old email addresses I had contacted to prove it is me (the ones I can remember anyway)

Anyway, a few days later I always get the response I have not provided enough information and I'm at a loss as to what I can do to prove it is me.

Could anybody help or point me in the right direction to help gain access.

Thank you so much in advance
