Opening a can to suggestion

Rotten and mouldy pet food in can upon opening. Due/bb date 2023.Complaint only apparently logged on 16/08/2021 when they received my pics via mail although it was reported almost 2 weeks ago. Still have the contents in fridge in my garage as Promeal has the option to make arrangements to collect if necessary. Haven't heard from them ever since. I am a very impatient person when I am treated in this manner as a consumer.,and I expect answers promptly.Clearly it needs investigation as the entire batch could be contaminated.
