Where's my refund?

I ordered the Hisense 26l Mirror Electronic M/Wave online on 7 August 2022. A week or so later I realised not all the buttons on the key pad works. Logged a refund on 20 August 2022. Return got processed, they were going to collect the microwave at my home, but that took too long so I suggested that I could just deliver it myself, Makro agreed. The staff at the Montague branch excepted the return. I received a refund invoice via email on 25 August 2022. The thing is, I'm still waiting for the money to be refunded to my account. We've passed the 7-14 working days for refunds to reflect.

I mean it's something so simple, I don't get this level of bad service from small side hustle online businesses.
