Thabong Sebokeng total garage

So I was at the Sebokeng total gas station the one right outside Thabong mall to shop for quarantine snacks and when I got to the till I was billed ridiculous prices from the ones that were displayed on the shelves when I requested for the manager the lady assisting me claimed to have been the manager and told me they mistakenly placed those prices and I asked how is it possible that half of the store has incorrect display prices she rudely said I'm either gonna take everything at the price she telling me or leave them and obviously with her attitude I left now I don't know how you people run your business but I've been a client to Total for years and have never experienced this kind of poor service where I stay I'm greatly disappointed.
