BAD SERVICE FROM A MANAGER THAT COULDN'T RESOLVE THE ISSUE

As I wanted to surprise my parents with a delicious caramel Swiss roll from Woolworths food at engen Croydon there was a price attached as I came to the till it wasn't scanning that price we were waiting on the manager to come that took so forever, she eneded up walking from one isle to the other and eventually came to the till and just said unfortunately she can't give it to me at the price it was advertised because it's not that Swiss roll I had no words after a manager told me that she can't do anything about it after she was the one that was placing the price tags on the displays. I have the image ga of the price, please request it.
