Hotmail hacked, password changed, unable to validate ownership

Hi

i am aware that this question is asked a lot and that every case is different.

My hotmail was hacked 3 weeks ago. The password was changed.

i followed the protocols to recover my account and validate ownership.

I completed the validation form with exactly the right information, but Microsoft continue to state that it is insufficient.

I have spoken to Live Chat agents numerous times and they informed me that I can validate my account manually.

I have requested this service but Microsoft refuse.

Is there anything else I can do?

Thankyou
