It is worrisome what is actual expiry of your product. In the Freezer, there are packs of the fish head. I don't believe ALL are of the same batch.
The staff whom i enquired said the frozen fish can last 1 year but enquiry to your website stated 1-2 months.
So what is ACTUAL expiry date ? Some packs had marker written nos like 19/1 .... What does that mean ? Prepared since Jan ?
I think there is no system NCOs there is simply no indication on each pack the preparation or expiry date, all packs are likely to be mixed up, fresh n old batch together.
