I went onto their website and looked at the product and there was no mention of it being anything other than normal low fat Greek yoghurt. I normally get the Chobani low fat Greek yoghurt and it has the texture of normal yoghurt, unlike the Tamar Valley stuff I bought which has the consistency of a thick milkshake. I messaged them out of curiosity to see if it was normal or just a small batch that had gone wrong. Apart from the semi-liquid state of it, the taste is quite normal.
You never know what response you will receive when you contact companies with a product enquiry. Some are relly good and practical; some others seem to think it's a defensive game where you run customers around n circles until they go away. I remember contacting one of the Italian anchovy manufacturers when I found shards of sharp white plastic in their product. I wasn't complaining, just bringing it to their attention and they were really appreciative of it. Funny thing is, I bought a jar in recent times and encountered the bits of sharp plastic again, a couple of years after the last time. Probably related to something like a plastic bush that wears and eventually breaks during processing.
