My account has been hacked, i need your help please

I cannot get into my hotmail.com account. It is a 15 year old account. Is there a number or an email where I can successfully treat this matter? I have applied questions here but always get replied with ridiculous answers that send me back to useless links which I have already said they do not WORK FOR ME. I have tried re-setting my password but it says I have insufficient information. I have provided the last emails I sent and the last contacts, all my old passwords, everything.  I don't know what to do. Can somebody help me in this matter. I am a medical student going through boards right now. This process is very frustrating. Nobody is able to help. And please do not respond with an unhelpful link.
