Eggs + MAGGOTS, FAECES, FEATHERS - and absolutely no response from supplier!

In December I bought 4 trays of 30 eggs to take with us on a family holiday. There were 11 of us together, hence the large number of eggs. The trays of eggs, purchased from Pick & Pay home shopping, were wrapped in cling wrap which was useful to transport them to our destination, so I never inspected them before we departed. Upon opening, not only did I discover that the eggs were filthy - with feathers and faeces stuck to many of them, but they were crawling with MAGGOTS!! On my return home on the 1 January 2021, I immediately logged a complaint by phone to the customer care line. I was told that the complaint was serious and someone would contact me. After 5 days I had heard nothing, so I contacted the Customer Care number again, only to be informed that my first complaint had been lost. There was no record of it. So on 6 January 2021, I logged a new complaint and sent photos and videos via Whatsapp to the number I was given. I included pictures and videos of the eggs and maggots, as well as my receipts for purchase of the eggs. I was given a new Reference number for my Complaint. I then waited a few weeks and during March/April I had still not heard anything!! I called again and (I did not record the date of this phone call) and was told that my complaint was "being dealt with". I am still waiting to hear from Nulaid!! 3 1/2 months later. Not a word!! I wish I could include the photos and videos of the 4 trays of eggs crawling with maggots and covered with faeces and feathers. I have a record of my WhatsApp correspondence with all photos and supporting receipts.
