Aldi autorecharge

I have an Aldi mobile plan for the first time. I have a one month plan expiring Mar 6, and have autorecharge enabled. Critical information summary states

"If you have Auto Recharge selected when your plan expires at midnight Sydney time we will process payment and renewal of your plan. This process can take up to 6 hours to complete, until the renewal for your plan is complete if you need to use your service you will need PAYG credit, otherwise you can recharge manually. if you need more information on how auto-recharge works and if its right for you please visit the following link https://www.aldimobile.com.au/autorecharge"

I have quite a bit of data left and would not like to lose it in case autorecharge fails?

What does everyone do?
