Magot in my pork chops

We bought pork meat at Spar Hunter PE on the 19th May 2023 on that sunday when i wanted to make the pork i found a magot in the pork i contact Spar immediately Manager told me that he will have the butchery manager contact me. Butchery manager told me he needs to investigate not sure what he needs to investigate as i send pics and video of the magot crawling on the pork chops. This is not the first time ive bought rotten meat. But what i cant understand meat was packed on the 19th we bought it the 20th. Now im still sitting with contaminated meat in my fridge at least sealed good. We always use spar to do daily shopping but i am very disappointed in the service lately. Going to report this to the health and safety as this is not right we stay out on smallholding and to drive all the way there to bring in meat is nit exceptable.
