Every single bundle you buy is yours, now and forever!
If you paid for a bundle this month, you will have access to it even if you decide to cancel your subscription for the next month. You can always come back later, but remember: the Loyalty Rewards are granted when you have bundles from consecutive months!
If for some reason you cannot access a specific Loot, first check if the payment has been approved, if it is necessary, verify your payment details (access How do I change my payment method?). If it is not the case, please, send an email to email@example.com.
