Can't access hotmail account - Please Help!!!!!

I cannot access my hotmail account. I've tried all passwords and questions but keeps coming up with 'The Microsoft account is incorrect. Please try again.' When I try to Create a new account with the same email it says the email address is in use and says something about the domain of hotmail not working or something.

I'm not to sure if this a fault on Microsofts point or hotmail but I believe now they are one of the same thing!

I majorly need help with this!! It causing much distress and I have tried various of ways to try get this matter resolved but nothing! 

Help help please, anyone!!
