I just attempted to place a $70 order with Big W using a mix of gift cards and Zip pay. Upon checking out, it was telling me that the payment method failed and to try another. I ignored that thinking it's just a bug and tried again with the same details. Same error.
I then tried to complete the checkout process from the beginning, only to notice that many of my gift cards had been redeemed (some did not get redeemed) and were no longer valid! AND my Zip account has been charged with an email from Zip "Your purchase at BIG W was successful"
So Big W has stolen my gift cards and fraudulently charged my Zip with NO successful order. I am extremely unimpressed and deeply disturbed by this. I cannot call them until tomorrow morning, but let this be a warning for anyone else - there is a serious issue with their checkout system.
so what did bigw say when you contacted them?
