Sir/Ma'am, you will be allowed to subscribe to a Combo pack when your Account Balance > Combo Pack Monthly Price + your current 1 day DBR. Else, you will be asked to recharge your account. Post subscription as well, your Combo pack will get renewed after each monthly cycle only if Account Balance > Combo Pack Monthly Price + your current 1 day DBR. Else, your Netflix Combo pack will go on hold and regular NCF (on DBR) will be attached to provide access to whatever additional content you would have subscribed to.
