Customer service complaint

Disappointed with their customer care service today, the ATM ran out of cash went inside to ask for cash got told that i must go to any till they have went to 3 tills all said they did not have money but you could see that they had the cash. Why are they there if they can't help. If pnp has special some of the items on special get removed from the shelf hence we end up going to Clearwater mall. Also be on the watch out from their till oparators they always add some amounts of things you didn't purchase which cost little amounts and give you change that's short. Last time my change eas was R13 short. So yes am disappointed and annoyed with pnp honey junction in Radiokop. Their cashier and supervisors really need to go for customer care service so that they get taught that a customer is a customer regardless of the colour of their skin
