Can i combine $1 and $2 rebate? or I have to remove one and add the other?
By reaching level 3 as a Fizz member, you will be able to combine these two discounts. To unlock the level 3 membre, you need to get rewards via different posisbilities (answering on the forum, paying your Fizz bills, adding things to your plan, inviting new friends etc.)
Otherwise, you will have to swap your two rebates and the new one will be applicable on your next monhtly payment.
the awnser is yes, but if you have more than one unlocked slots.
does this mean I have to remove the $1 and load the $2?
You can, but the first will be in pending to be retired for a paiement cycle, and the second will be actived after another paiement cycle. So you better unlock the second slot...
If I remove a perk, I lose it for ever or it back in inventory ?
If you SWAP them, you'll get back in the inventory. If you delete it before putting the other one, the one deleted is forever deleted (not 100% sure).
Better to swap them, but longer to apply the bonus.
