Pecks Anchovette fish paste

Bought Pecks anchovette fish paste at Makro Woodmead,the last week of December 2024. Expiry date :03.06.26 Barcode :*** Today when I opened the bottle of fish paste, the top of the contents, is mouldly. (White stuff) I'm really annoyed, because I was ready to enjoy my toast with my favorite paste.. PS:I have. evidence /proof of the above.
