My premium was up for renewal and it tried to charge my card. However payment failed as I have insufficient funds in my card. I was intending to cancel the premium subscription anyway. Is there anything I need to do or I can leave it as such? I don't see a way to remove my linked card in the account. Or cancel subscription since my subscription lapsed already. My fear is that once I load funds into the card, it will retry payment and deduct money,
