May I please get my refund.

I made an order yesterday 20/05/2024 on the Pick n Pay ASAP app for 2x 5kg Iwisa maize meal and Jungle Oats. When my order was processed and on its way to delivery I received a notification that I was going to be refunded R109.98 for the Iwisa maize meal which was sold out. Once I realised this I made a call to customer service to cancel the order (because that is what I initially wanted to order) I was assured that the order was cancelled, however, the order still arrived to which I communicated with the driver these new developments. On the App it states that my order has been delivered which I did not open nor collect and I was not refunded for that cancelled order & delivery fee as per the call with customer service. It is inconveniencing to order an item where it is not indicated that it is sold out whilst placing the order or replaced with alternative items upon collection. Please assist in attending to this matter.
