BAD PRODUCT

I hope my email finds you well. I hereby wish to lodge a formal complaint regarding a certain product that I purchased yesterday (04/01/2022) from Pick n Pay in killarney. I bought the Divine Double Cream Yoghurt (strawberry cheesecake flavor) which I found to be the disgusting this ever, I looks and tastes off with sour lumps inside and smells really bad. Doesn’t even look like double cream at all because it’s so runny I know this because I buy this brand every week (as a Double Cream Yogurt FREAK). This is really a health hazard and needs to be addressed and rectified please before more people get really sick as I have a really sore tummy now. I have attached the product and till slip, I have the BB date on the pictures and well as the date of purchase on the till slip. Please can someone help me regarding this matter, thanks.
