Locked out of my account….

I inadvertently changed my year of birth on my hotmail account to 2013, and now I am locked out and unable to access my account without a parental log in.  It does not give me the option to return to my DOB drop down box, and when I sign in with another “parent” email, it prompts me to enter a credit card number to verify my age (>18).  I have contacted the chat support and filled out the age verification form, but it was, apparently, for the subscription version of hotmail.  I acknowledge that I am technologically illiterate, and the forum is much more advanced that my ability, however, as I am not, in fact, a nine month old infant attempting to operate an email account, I would like to be able to access my own hotmail account.  As previously stated, I am behind the curve when it comes to technology, and specifically, computers.  Please type slowly and with very “dumbed-down” terminology.  Please and Thanks!
