Meat World threatening a consumer who attempted to expose the truth about them (with proof)

I bought two sealed packets of pressed tongue from Meat World. I had already consumed one of the packets when I noticed a foreign object in the second packet. Upon closer inspection I realized it was some sort of a fly (Photos attached). I immediately lodged a complaint with Meat world. In my complaint I expressed my dissatisfaction with their product and also commented that I want to see what action are taken to ensure this never happens again. Meat world then contacted me and told me that they found the guilty Quality Controller, and that it was a white lady, and that they will be taking disciplinary action against her. They then asked if I will testify against the employee at the hearing. I refused to testify since this is an internal matter and offered to provide them with a signed statement if needed. I was only interested in seeing how they are going to prevent this from happening again. I even stated that I do not want the employee dismissed and that the dismissal of the employee would not prevent this from happening since that is not the root cause of the problem in my opinion. I then left the matter and awaited the outcome and conclusion of my complaint. They conveniently never communicated anything regarding the outcome of my complaint to me.

This happened more than a years ago, and nothing had come of it. Since I recently became aware of a similar incident and civil cases are only valid for 3 years, I decided to follow up on the complaint and investigate why this complaint was never resolved. I posted a review of the complaint and my dissatisfaction that it was essentially ignored, on their Facebook page.

A couple of weeks later a received a letter from their attorney threatening me to keep quiet about the incident or they will take legal action against me and claim damages.

I might be wrong, but I find it highly unjustified that I, as the victim in this, am now being threatened if i don't keep quiet about the foreign object I found in their product. I have also been made aware by their attorney today that they will be instituting legal action against me for the public post regarding the incident.

For the time being I will ignore section 55 and 61 of the CPA which is supposed to protect me in this matter. I refer to section Section 2 of the Food, Cosmetics and Disinfectants Act- it is a ******** OFFENCE to sell or distribute food which is unfit for consumption or which has a foreign object in the packaging. This ******** conduct can be attributed to any party in the supply chain from importer, manufacturer, distributor, retailer, to food outlet regardless of actual knowledge of the foreign object in the food or the state of the foodstuff.

Yet Meat World is trying to treat ME like a ******** for creating public awareness regarding this disgusting incident.

And this is not from some branch manager. These are the action of Mr. Pereira who claims to be the C.E.O. of Meat World.
