No refund from Woolworths online

in the beginning of shutdown I ordered some groceries online. the booking slot was for the following week when I booked however things charged and was told my order would be delivered mid April. I bought my groceries end of April. After numerous calls I still have not received my money to this day.

I was told by one of the call centre people to call my bank and ask them to release the money. I called capitec and was told that they do nor see the money on their end. they are still investigating with woolworths. not a single call from either of these companies about my R900+.
