Rotten Waggies dog food

I bought 4 bags of Waggies senior dog food in January 2025. When I opened the first bag, the food was covered in mould, and I had to dump the entire bag in the ******* bin. I opened the second bag, which seems fine. However, this morning when I opened bags 3 and 4, both were filled with mould covered dog food. I noticed then that the food expired in February 2025. (Bought it at Pick n Pay, but obviously I no longer have the receipt.) However, note that I opened the first bag prior to the expiry date, and it was already rotten, and would have negatively impacted my senior dog's health. I cannot find contact details for Gourmet Industry, the manufacturer of Waggies, but I did find MANY similar complaints on HelloPeter website.
