Immediate cancellation of subscription
I erroneously clicked on subscription of an app but cancelled immediately but it says expires on the 7th of December.
Question marked as
Unless there's a free trial I believe that subscriptions start immediately and there is no cancellation grace period. You have canceled now, and it is canceled, but will run until the end of its current period.
Note that it is very difficult to "erroneously" subscribe. You have to do multiple very deliberate steps. The best you could do now would be to ask for a refund, but that is not guaranteed.
