Woolworths took my money and never refunded it back. Don't use Woolies Dash because you will be ****med of your funds

Last week I ordered groceries on Woolies Dash and R904 from my bank account was deducted. Not all the items were delivered so another amount was deducted for R761.47 for only what was given to me. The first amount was never refunded so I called Woolworths and asked them to please sort it out and they gave me some excuse about how the bank is supposed to reverse the transaction. I called my bank and they said there is no pending payment on their side and that Woolworths is responsible. Now I am missing almost a R1000 and no one wants to take responsibility?? I am extremely disappointed with Woolworths. This needs to be sorted out immediately as this is nonsense now that no one knows what is going on. Its just pure incompetence from such a "reputable" retailer.
