Hi! Sorry to hear that you have troubles with this situation, have you use the cancel subscription option or you just stop the renewal, in case you do the second, you could still see the subscription active in game as it will remain like that until the end of the period that is already payed.
If you chose cancellation, and the Microsoft site shows it as cancelled, then you need to contact Epic support, specially if you purchase it in game and not trough the Microsoft store.
