False advertising at Pick n Pay Diepkloof Square

Pick n Pay Diepkloof Square is a nightmare!!! If you don't wait for literally 5 hours in their cues then it's false advertising. For instance I just bought a 250ml Lazenby Worcester sauce today,on the shelf the price was R27.99 now I'm at home checking my slip and I was charged R30.05. This the second time it happens to me and probably to many more customers who aren't aware of this. Food is expensive as it is and now I get ****** of my cents on top of that?? No maaan this store sucks big time I'm disappointed to say the least
