WORM IN YOGHIURT - WOOLWORTHS

I purchased yoghurts ( Ashyire Brand) form the Woollies store on North Rand road Boksburg JHB yesterday and the expiry date for one was the 16/4 and the other the 23/4. The muesli is rotten with mould and there's a worm inside. I have taken pictures that I can send through. <br> <br> I work in The Quality department at my company and I TOTALLY understand the word Quality and SERVICE when dealing with customers, surely Woolworths should know the same. <br>
