Arrogance, Bad Customer Service

After doing shopping nd spending over R200, I saw 3 items which i wanted to purchase.The items was clearly marked at R4.05 when I wanted to pay the teller told me that it was R10.00 each. I told them that I would like to speak the manager as the items was clearly marked and thats the price I want to pay. He inturned advised that he is busy and he does not have time for petty customers. This being me? Really sad that a so called manager has such an additude, and calling clients petty. He didn't even bother to come and speak to me he informed the teller to advise me to either take it or leave it! Wow! I had no words for such arrogance from a manager. Sad to have people like that at management level, they suppose to be management nd resolve customer issues. I do have pictures of the items and the marked pricing.Such blatant poor / Bad customer service.
