SkyDrive Account Lockout

I have been locked out of my SkyDrive account. 

I tried to log on and access my files from a "new device" (This being my current Surface2, since the account originally was created on a different Surface2)

When attempting logon, I recieved a message from SkyDrive saying "Confirm Security Information", but when I did this, it just sent me a code which it wouldn't accept.

I then altered my "Security Device Settings" and set it to "Phone" instead of "Email". This resulted in a 30 day lock of my account due to "Security reasons".

My problem is that I have put all my things in my SkyDrive - I need to access it in order to teach my students.

Can anyone help me resolve this issue?

(I have already contacted Surface Support Desk and was referred to post here)

Kind Regards
