Animal care issues

I’m looking for some advice. I work in a store as management (leaving out title for reasons) and I have some issues about our animal care. The mice look like they haven’t been cleaned in weeks and have pee built up EVERYWHERE, every bird we have has a massive pile of poop in their cages, the tree frogs had a massive pile of poop in their enclosure, fish tanks are EMBARRASSING, etc. I don’t know where to go; I don’t trust the GM or the DGM to actually do anything about it. Any advice is appreciated
