Absolutely disgusted

I placed an order ***2 on 28th Feb 2022. There was a special for tinkies box R10 per box and save R29.99. I bought 8 boxes. Afterwards I checked I was charged for the full price and discounted R80 only instead of being charged a total of R80 only. When I logged it, they then went and changed it. I have screenshots however of the R10 special. I still haven't received my refund and to wait for my own money is becoming quite appalling. Raul from the support center told me he escalated it to his manager and his waiting for feedback, that was Thursday 03 March. Nothing since then. Why do I need to fight for my own money. I want this resolved immediately and my R239.92 refunded to my bank card!!! Extra savings card: *** Incident reference: ***
