No Vouchers due to a typo on their side

I have been a loyal Woolworths customer for the past 2 years and decided to upgrade my Wrewards card to a Wstore card. During this process a staff member at Woolworths made a typing error when transferring my email address on to the system. Due to this my card is not linking up to my WApp as well as my online profile and as a result they are not functioning properly in the way that I do not get any of the additional vouchers for being a loyal Woolworths shopper. - The vouchers that even shoppers with regular Wrewards cards receive.

Woolworths has been failing to resolve this issue, despite my even visiting the store and having a very helpful staff member there assist me in dealing with the rewards and accounts departments.

At this stage I wish I rather stuck with purchasing groceries from eBucks partners, as I wouldn't have lost out on such a vast amount of savings as I have in Woolworths failing to report and fix this problem...

Seriously considering closing my Woolworths account.
