Woolworths Online

I shopped online to the value of R16 000+ for groceries amidst of the red lights (signs) before - Woolworths not delivering on the day and slot selected that I had to call them or delivering wrong things. However, I kept on giving them the benefit of the doubt. They messed up my order by delivering wrong items claiming that I had selected "yes" to substitution. They substituted items that were not in stock with something that is far off to what I had selected. They sent the items the day after that, still they were wrong. Fast Forward, the local store (Centurion) called to tell me that they will refund the money for the items not in stock as I had returned them. I still have not received any correspondence. This is utterly nonsense.
