Dishonest trade, False Advertising

They advertise things on the shelf for one price but when you get to the till it's much more than that. This is dishonest trade and false advertising. When asking the manager he first said \system problem\" and when I asked for the owner all the managers ganged up on me and threatened me and told me not to create problems for them. This store is run very *********ly and I expect someone to get back to me with some sort of apology or I WILL NOT LEAVE IT HERE"
