Refund me immediately, else I will report this to the customer services ombuds

On 26 March 2023, I placed an order on the pick n pay asap App. Pnp did not have stock of 12 items which I ordered, my refund was sent to my pnp asap wallet and then I proceeded to withdraw my cash of R286. To date pnp has not refunded/deposited my refund into my Nedbank bank account nor have they contacted me to advise on the delay.... I have emailed pnp on 11 April to enquire and they rep**** that it would take 5 to 10 working days. Today 17 April 2023 and I still didn't receive my refund, hence I called the customer services centre and was advised by the consultant that they are on a back log. Which is really not my problem as a customer, having to wait for more than half the month for a refund of funds that was allocated for groceries is ridiculous. The delivery service is called asap but pnp fails to understand that the groceries that are ordered are also required ASAP, hence pnp has no right to delay a customer's refund and it has now been more than 20 days. I will definitely not be using this service ever and will recommend my friends and family against the use of this delivery service. Pick n pay need to respond n refund me immediately. The two references which I was given are included for your reference ***. ***.
