Pick n Pay Overcharging

I'm so sick and tired of PnP's consistently poor service and constantly overcharging on the ASAP app. I was forced to remove about 6 items that were out of stock. The cheese that was R129.99 on special arrived marked R149.99 which I was charged in full. It's a small amount, I know but this keeps happening and I don't bother complaining but I'm fed up because all these little things add up expecially when you consider how many customers they are doing it to.
