I’ve got an issue to raise regarding your processed sliced Gouda cheese

I’ve got an issue to raise regarding your processed sliced Gouda cheese. I’m a regular customer at your shop in silverton just next to Eskort The cheese tastes rotten and sour ,the taste is off I even had to make 4 people taste it just to make sure it’s not my tastebuds sadly it’s not my taste buds. I’m really disappointed with your product,as I recommend it as the best quality cheese. Hope you find it in your heart to read the text. Thank you
