Concern about sm supermarket

Hello! Wanna ask about something po. Bumili kase kami ng frozen food sa sm supermarket edsa. Crispy burger and there's a lot of mold on it poo then we already lose po yung receipt kase May 2, 2026 pa namin siya binili then ngayon lang namin kakainin sana. Kase we always put some food sa ref namin then ito lang yung unang naka bili kami ng may mold. Pano po kaya gawin para ma report sila or pwede pa po ba ibalik yun?even without a receipt?
