Daylight *******

On 2023.04.21 I bought 2 x Spring water @ R23.98 and 2 x Country class Boerewors @ R74.00 and PNP charge me R1.15 for a bag but had my own bag. The total was R99.13. I lay a complaint and they give me back R1.10 but not the R0.05. Which means they ****** me of a five cent. Pnp owe me 0.05 cent. If they take that much of each customer,they make millions. I want my 5cent back.
