False adverti*****t

I bought an item at this shop as advertised in the pamphlet. At the till the item scans a different price and has a different name even though the item is exactly the same as the one advertised. The manager however gave me an attitude instead of trying to resolve the problem. I have a problem with the way this particular item has been advertised because it seems to be a false adverti*****t. What I find even more disturbing is the attitude of the manager in this store.
