C***** Berg Cheese Disgusting

I am really appalled by C*****'s block of Berg cheese that I bought last week. The cheese is not of a good consistency and crumbles when you try to slice or grate it. It is certainly not cheddar and tastes horrible. I have tried it on sandwiches, tried toasties, tried pizza...The cheese does not melt doesn't matter how hot or long you grill it for. Just does not melt. Am super disgusted by C***** and certainly will think twice before buying any of my USUAL C***** products. What kind of cheese is this? not even sure I can blame it on the medium fat as I know most other medium cheeses are tasty. 800g of cheese to go feed the mice at the park with.
