Misleading Pricing

On Saturday 8.04.2023 i visited PnP and the BUZZ Shopping Center. From the height I was looking from I noticed Speckled Eggs priced at R 18.99, when the cashier scanned a price of R 109 .00 appeared, I queried this and was told by the manager that the merchandiser forgot to remove the price tag. The attitude of the Manager was aggressive and rude. Is this not against PnP policy ? What happened to Pick n Pay's Double the Difference Policy & how many customers actually compare bare codes or IS THIS NOT FALSE ADVERTISING ie. Making old age/poor sited people purchase "In good Faith"
