refund my account already

Good day, On the 25th I placed an order and paid R1 011, it got delivered on the 26th, not all items were delivered and total on my picknpay profile is R910.86 which makes sense cos some items weren’t delivered, question is when will I get refunded back my R100.14 for the items not delivered? https://www.pnp.co.za/my-account/order/***
