6 double cream plain yoghurt leaking and bought at pick n pay Qualisave

I bought a six pack double cream plain yoghurt and there were leaking I sent an email no response and I even called logged a case I was given a reference number and told to send photos proof that it was their products and I should do so via WhatsApp thentold me I'd get a call within 72 hours till today.... Ref. No. 24/03/309 Parmalat doesn't care about their customers and yet what if that product was contaminated and I had food poisoning so disappointed in this big company
