Parental Lock on Adult Account

I tried to buy the gamepass but it wouldn't let me saying that "You need an adult to buy this". A quick google search said something about a family group and when I checked it showed I was in one, since the email of the family organizer is inaccessible and will remain that way I left the family group. I tried again to buy it but it showed the same alert. I read somewhere else that child restrictions are lifted when the account owner becomes an adult according to the given info, that doesn't seem to be the case since according to microsoft's own info I'm well over 18. I'm on PC. I tried to get a live support chat started but it doesn't seem possible. Any help would be appreciated.
