Forced into Outlook, don’t understand billing

Because of a billing problem, I was apparently forced out of Hotmail Plus into Outlook, and cancelled from Hotmail in September. All my old email is now accessed through Outlook, and today when I finally replaced my account's credit card, I was immediately charged $19.95. I seem to have a new anniversary date for my subscription and don't know if I can get back on Hotmail, which I would much prefer. Can anything be done? This is frustrating because the original problem was not of my doing. My credit card company issued a new card number to me because of security concerns, and my old number could not be charged by Microsoft.
