Incorrect order no feedback

I purchased ice cream, two 2-litre Cokes, and four Monster energy drinks yesterday at around 6:30pm from pick n pay. By 7:30pm, my order was delivered, but with incorrect items that appeared to belong to someone else.

I immediately reported the issue on the app and only received an automated support email acknowledging my complaint. Since then, there has been no further communication regarding my refund or how this matter will be resolved. It is now almost 10:30am the following day, and I find it unfair that I have to keep chasing for a resolution to an issue caused on your side
