Scratched off digits, no CVV and the magnetic stripe doesn’t work? That’s 100% a tampered card. Believe it or not but it’s possible to open up the packaging and reseal it without leaving any visible signs.They are being replaced. Not tampered, packs were all correctly intact. Just misprinted cards that shouldnt have made it through QC.
I’ve studied this scam quite a lot and have bought tampered cards myself. You can go through the gift card company but in my experience they’re very slow and tedious to deal with. Emailing the Woolworths Gift Cards customer care team photos of your gift card and receipt is the fastest way to get a refund.
