told to **** off

I went into superspar Five ways mall Empangeni. The item is purchased scanned incorrectly at the till. I as a client am supposed to carry a bar scanner to guess spars prices. The item was marked R 41. 99. Scanned at till to be 79.99. Long story short, some short Indian dude came with me to the aisle. Insists that one item has two prices and the one I took was not the one. When asked where it was, he could not show me and then told me to **** off. Upon leaving, I told the cashier to tell him that he can **** off as I will not purchase from them, to which he rep****, same to you. What lovely customer service from *********** idiots.
