Woolies commits ***** on my bank account

Woolies dash is trash! Second time now that I order food and my item isn’t delivered because they “out of stock” yet the item showed “in stock “ when I ordered it. And to top it off instead of Woolies refunding me they debit my account for the item again! This is ********** Woolies! I never authorised you to debit my account! How is possible when I’m supposed to provide my ccv card details before I purchase something? But yet Woolies can debit my account whenever they like? I’m so disappointed and disgusted with Woolies. Don’t use this online delivery service if you don’t want to be ****** of your money! I will be raising a case of ********** activity on my account Woolies and you still owe me my monies you *******!!
