False Advertising in store and overcharging

I visited Pick n pay benmore gardens on the 30tht January 2019. I purchased quite a few items and saw that there was a special for bacon being advertised in store. I grabbed the two packets of bacon and place din my trolley. When done with the shopping , I proceeded to the till and paid. When I got home i noticed that I was charged incorrectly fro the bacon, the special was not app****.

I immediately emailed the pnp customer service mailbox when double checking my slip. I received no response form Pick n pay. Then today I receive a mail stating that my complaint on the pricing issues has been resolved. How can they resolve the issue without even contacting me?

There are alwas specials advertise din store at Pick n pay then when you get to the till the specials are not app****. Either someone is not doing their jobs by removing the special in time or pick n pay is just plainly falsely advertising and *****ing from their customers.
