if you recently activated your new Public Mobile account, you had to use a valid credit / debit payment method and by default it was set to Subscribed (...which is Autopay). Every 30 days, your account will renew and use that card for any balance owing. If you want to manually pay using vouchers or some other method, you can log in to your account to disable Subscribed (...which is Autopay). Just remember to get vouchers at the retail level ...7-11, Shell gas and London Drug to name a few...then you can dial 611 to add them to your account for renewals.
