Woolworths deliberately causes anguish and sabotage!

Last week I wrote a review regarding Woolworths pathetic customer care service which displays a poor work ethic, and a lack of respect for consumers. To date, the issue is not resolved! Woolies had the audacity to send me a used voucher, thereby failing to actually refund me for my wasted purchase. Once Neo and Karen at Woolies Ninapark became aware of the scenario, they undertook to investigate and revert to me. That was 5 days ago, and to date, I've never heard back from them. Surely Woolworths staff can't be that stupid to send an already disgruntled consumer, a used voucher!! Yet they did! I've been going around in circles for several weeks trying to get a resolve on the matter, but Woolworths evidently doesn't care, and delights in embarrassing their consumers and wasting their time, by causing such in store inconveniences! I feel as though Customer Care is deliberately causing such anguish and sabotage, since it's virtually impossible to make such errors when there is email references in place, which they can easily refer to, in order to rectify if they indeed wanted to!
