Pnp head office please intervene at pnp family store protea glen mall

I am constantly disappointed by the customer service at pnp family store in protea glen mall, there's a floor manager by the name of Nkhandzeni he is always rude to customers and no action is taken no matter how many times u complain about him, can the head office intervene in this matter cos he verbally abuses customers when they have a query regarding a pnp product. Today I went to buy double cream 6pm yogurts and they were priced less on the shelf and when i demanded to pay for the price i saw on the shelf fridge, he started being rude to me in front of other customers, telling me I like cheap things and I don't understand why I shouldn't pay for the price I see, since it's their job to make sure the prices are correct to avoid misunderstanding. This guy should be moved from pnp family store protea glen to another store, I am not even comfortable shopping there and its the only pnp closer to me, people always complain about his behavior but no help.
