Mouldy milkbones, limited response from Marlton's

On 7 Nov I sent Marlton's a message about their milkbones dog snack, after I opened a bag of it that I bought the week before and noticed mould on some of the milkbones. The expiry date on that pack was 17 Oct 2026. I got a reply from them three days later (10 Nov) asking for photos of the batch number and proof of purchase, which I sent on the same day. On 18 Nov I sent a follow up together with more photos of other mouldy milkbones I saw in the same shop where I bought the previous bag - - the products had not been pulled yet. Received no reply thus far - today's date is 25 Nov. On 21 Nov I visited the same shop and still found mouldy milkbones. I then reported it to the shop management. Apparently Marlton's does not see the urgency in pulling mouldy dog snacks from shelves.
