Pathetic customer service

Bad customer service, been in contact via email. When I found maggots in puppy food was told noyly maggots but weevil larvae. I don't care what they are they are in the food. Sent pictures, it was before best before date and the years shelf life but no compensation. I did not want anything,but now I do. As it was made out to look as if we did not store the food correctly. Supported them for 8 years since we got our min pin(he is 8 years and still eats the puppy food and it's small enough for hin to chew without biting himself). I buy the puppy and the maintenance for the bigger dogs. And this is the first time I have had this ****. You don't blame the customer who is supporting your product for the flour or the maize that gets put into the food. It's shelf life is year and it's not a year t and the maggots are inside the bag and the container which we use. I do expect reimbur*****t as I will not leave this. My wife was very patient but after the emails received stating they cannot reimburse due to they way the food is stored and and and bull****. The fact is the Dog food is not over its shelf life and it is before its before date. I had thrown away more than half a bag of 10kg puppy food. Please see see emails between my wife ,Freddie and Charne.
