Smokey Joe Tin full of oil

I bought a tin of Smokey Joe dog food (big one) for my dogs. When I opened it, half the tin was full of oil - I could not give that to my dogs. I contacted them on 4 August 2024 - they rep**** on 26 Aug, 27 Aug and 5 September with: "we are investigating".

What is there to investigate??????? I bought the dog food (that is quite expensive!) and I attached pictures with my mails - what is there to investigate for more than 2 months already with no replies or outcome????
