Hi, is anyone here familiar with the way the parental settings work on microsoft accounts?

i've had this account since i was about 13 years old, i'm now 18 and i thought by now they would just automaticly remove themselves. You see i vaguely remember creating a 'fake' account as a parent because it wouldn't let me sign up to something, not sure what. but now i've just brought a windows phone and there are some songs that it won't let me preview because of these 'family safty' settings or whatever.

the problem is that i can't remember what the email address or password to this 'fake' parent account i created.

is there someone from microsoft here who can remove this for me or does someone have a number i can call to get it fixed?
