Last week, I opened my email only to be met with a message telling me that someone is using my account. So, I requested the code as prompted on screen.... and it never came. And as such, my email account is now blocked. In addition, as I've been in contact with the (useless) support team for two weeks now, I've been informed that my backup email is not the same. This is highly unlikely.

My email at live.com contains sensitive information as well as is linked to all my major transactions. As such, it is imperative that it is returned to me ASAP. I did attempt to fill in the form at https://account.live.com/acsr, but I am unable to completely do so due to not remembering, which is understandable given this account was made when I was still a child.
This is extremely frustrating, especially since this also renders Skydrive, where my important documents are stored, inactive.

I have provided alternative solutions, such as evidence from Steam receipts within the blocked email, but they fall on deaf ears, as apparently because Microsoft takes my security so "seriously", they are unable to accept nothing other than the form.

Now, I've filled in the form umpteen times already, and I've received countless replies, which all contain the same message that "automated system has deemed the information insufficient", as such, none of my entries have been taken seriously. Then again, the question asked mostly pertain to these:

Name any subfolders you have created other than the default (junk, inbox etc). My reply: NONE.

Name subjects and contacts who you've recently emailed. My reply: Again, NONE. I use this email for verification purposes, as well as an archive of purchase records.

Microsoft ironically suggests asking contacts for answers to the form if I cannot fill it in. But it was also Microsoft that suggested never to reveal personal information to others in the first place, so obviously that isn't going to help.

As such, I request the assistance of someone who can actually THINK instead of a support crew that only resorts to standardised answers (nearly 20 of them) in response to my queries, which are painstakingly typed out.

Thank you.
