Being randomly added to the beta while not even having the Xbox insider hub

On November 30th when I was suppose to receive the caves and cliffs part 2 update (1.18) but instead I was met with the beta installed. Before this I had never installed the Xbox insider hub and even thought about installing the beta - I now cannot leave the beta even after completing all the steps on the FAQ (note I know there are already bug for reports for not being able to leave but I believe this is different enough to warrant a report)In summary i was added to the beta without signing up
