We utilise a coupon if users return there used packaging we send out free gift
we populate “allowed customer list” with the customer as soon as we receive the returned packaging
what we cannot do is monitor who has utilised the auto coupon, I know we can do “one time use” but i would like to keep the auto coupon always for all customers even if they return once a week.
So The Question:
How Can I programmatically remove customer from allowed list?
I can check on thank you page if coupon used i just need snippet of remove from allowed list so i can re add them when i wish too on there next packaging return
