False advertising - Rude tellers

I purchased Easter eggs last week as per the special of receiving 25% off, on getting home and looking at my receipt I noticed that I never received the 25% off a fair amount of them.

The cashier herself did not greet me, there was no one packing the goods. My groceries were just pushed to the end and I had to pack the bags, I have the receipt and I am sure you have videos to see the way my stuff was handled. I got home to find some of the easter eggs broken because of the way they had been pushed around.

I do not shop at Pick n pay in general any more as I find Checkers has a wider selection, with more reasonable prices and the service on a whole is better. But went to PnP solely for the Easter egg special, yet once again terrible service. I have complained to Nolan Logan on several occasions. Yet nothing seems to be done.
