Woolworths Mobile Rewards Card Discount and GC Recharge

Hi all,

I am looking to move to a prepaid sim card using the Telstra network.
Woolworths mobile seems a contender along with ALDI and Boost.
I have read that if you link your Rewards Card when you recharge, you get 10% off. Unable to find this on woolworths website.
Also i am unsure if you can use your 5% off gift card to autocharge the plan - rather not have to recharge manually monthly. or is there a way for recharges to "stack"?
Does anyone use woolworths mobile? any shared experience would be great!

Cheers
