Pick n Pay Estcourt are *******, they over charge

i purchased items to the value of R1003.00. On the till slip there were 4 items that were incorrectly priced namely, braai bulk pack - shelf price R89/kg till price-R114/kg, PNP bulk salad 400g shelf price R24.95 till price R30.95,McCain baby peas shelf price R38.99/kg till price R39.99,white pepper 50g shelf price R21 till price R23.99.I approached the manager Ian,who threatened to assault me.He asked me to come with him to his office and he will \F"me up and teach me a lesson.He pushed me out of his store and said that he will never allow me to shop there again.He said that he will practice his rights and make sure that i never shop at his store again. He made it quite clear that he owned the store and he could do what ever he wants.I did not make the pricing mistakes"
