First time using their promotion, I saved the spend $100 and get $10 back on 29/6 morning then spent more than $100 on 29/6 afternoon.
My Paypal and JB Hi Fi invoice also showed purchase on 29/6. JB Hi Fi also sent me a link for special deal from Livechat on 29/6.
Amex shows transition on 28/6 and they decided not to give $10 back because I saved it on 29/6 morning.
I understand that I need to save it first to get credit but their system is showing the wrong purchase date.
If you are using their promotion, make sure you saved 24 hours before using it. Their system must have issues.
If you are waiting for credit back, please contact them directly.
Good luck
Update Amex explained I cannot use paypal for promotion and I accepted that.
They just said they are using MST (Mountain standard time) on transaction but seems using AEST for saving the promotion
Once again, make sure you saved it for 24 hours before using it.
PayPal?
