The microsoft account associated with this profile is invalid

Whenever I try to sign in with my profile "Ribstack" I get the message. "Your parents microsoft account isn't valid. Your parent needs to choose a different account to manage your xbox profile". I don't understand why I am receiving this message, my microsoft account lets me log into the xbox website, but when I use it to sign in on the xbox it tells me that the parent and child account cannot use the same account. This is curious as I am unsure why my "parent account" has decided to stop working. I know which account is the one that is my parent account as this email receives messages when I have bought microsoft points, for example. When I follow the onscreen instructions it lets me get to the final stage but then tells me that xbox live signup is currently unavailable. I have tried even using a brand new account that I made up, it is properly registered and accepted by microsft. However as I do the process of changing the parent account and I get to a certain point in the process, I am given the option to press continue, when i press the A button nothing happens, it makes the sound as though I pressed it. The console has not crashed as I can still use the B button to go back and the dashboard button still works. I have no idea why this is happening to me and I have no idea how to fix the issue. I have contacted numerous people on the support chat function. I have been told that I am waiting to be contacted by the advocacy team but am still waiting for a response. Any guidance, solutions or even telling me that I am not the only one would be much appreciated.
