Missing items

There was a special Pick n Pay was running on ASAP app where I purchased 2 JC le Roux bottles and I was supposed to get the 6 pack of cans for free. I purchased these as I saw it was a bargain, the driver got here and the 6 pack was not there. I immediately contacted them and they gave me a run around about items being out of stock which is something I do not understand if the items were out of stock they should have marked the items just like the bacon I wanted to buy and it was marked out of stock. I am really disappointed at this. I was supposed to save on the order and if it was marked as out of stock I was gonna buy something else. They responded on this and said someone will call me. I never received any call, I want this to be corrected.
