No options to recovery my email account

I can't access my Hotmail account. I am pretty sure my account has been hacked. When I tried logging in using my password but tried too many times and failed. I have never had issues before. Now I am blocked from it. I have tried to reset my password using other options. The security question is "Default security question?", which I am assuming is there because I never picked a security question. I don't know the answer to it. I have tried to recover it using the survey option and it says it can't verify me. I have called tech support several times and they gave me all the same spill and have gotten no where. To add to the mess this account is linked to my Xbox live account which now I can't get on to because I have to pass a security check. I can't access any of my saved games and all my purchased content. I have spoke with tech support at Xbox and once again back to square one. This problem has been going on for some time now. I am completely frustrated with all of this.
