Review Anytime chocloated coated peanuts

I am not too sure where to lodge a complaint.... I recently purchased a packet of Beacon Anytime chocolate coated peanuts from our local Supermarket, only to discover that the bulk of the pack's peanuts are RAW (not dry and crispy). Details of the batch is as follows: MAN21/05/2019 BB21/06/2020 13:39 D TW23.
I purchase this product quite regularly and thought to advise you such that you could take the necessary remedial action. I have been involved in the food industry for many years and do realise that customer feedback, albeit negative, is always appreciated and often proves to be extremely valuable.
