Hi. After trial subscription is expired, we've paid for subscription in store by our master card #1. But when it's expired in a month, we're not going to use this card, we're going to pay by our mastercard #2. The question is: how to cancel this current payment method (without knowing details of our mastercard #2 because we haven't get it yet) ?
And the second question: what means button "cancel" ( after "Next Billing Plan*:* Takes effect on your Next Billing Date * Change Billing Options* " ) ? Does it cancel payment method or does it "freeze" subscription (or cancels subscription - but I don't understand,if we've already paid money, what's the reason to cancel ?...) or something else ?
