Ridiculous Service At Marko Germiston

I went looking for a bottle of wine specifically advertised in the newspaper. I couldn't find it anywhere and there was not a single employee in the aisles to assist so after going up and down, I eventually found the case on my own but not the magnum bottle that was supposed to be included. When I went to pay, I asked the teller about it, she looked boredly at me and told me I'm supposed to bring it to her, I said I can't find it anywhere and she just looked at me annoyed and waited for me to take it out for her to scan through anyway so I asked if she knows if there's anyone who knows where to find it. She promptly called the supervisor. The supervisor just said "we don't have it" to which I asked, "are you getting stock?" Her response was simply an annoyed shrug and "I don't know" and she walked away. When I said I'm not taking the case, the teller just looked at me and I had to take the case back to the shelf all on my own while the other people in the queue behind me waited, not so patiently for me to take it back and then come back to purchase the rest of my stuff. So everyone's time was wasted while I carried a 12 bottle case of wine to the other side of the store. I asked where the floor staff is and was told "on lunch". How is the entire floor staff on lunch? And since when is it ok for a teller to expect you to just do everything while she sits and looks as if us being there is just annoying her.
