Less then the labeled contents

Hi I bought four wheels of melrose cheese wedges which supposed to contain 12 wedges in each wheel to my surprise after opening the first sealed container it only had 10 wedges in it. Please do not be ridiculous and ask me for a Picture because it's already opened and it won't be possible for me to send you a picture of the sealed container containing only 10wedges. This is really ridiculous because how do I recover what I paid for but did not receive to the company it might seem like a small issue but it really a misrepresentation of what I actually paid for and this not on. I work hard for the money that I earn only to buy a product and not get the quantity I actually paid for.
