No more Parmalat products for me

I am highly disgusted in the service received from Parmalat. I bought a six pack of long life full cream Parmalat milk and all six were curdled. I contacted the customer care and although they were very apologetic and said they would collect the milk and replace it, a month down the line I STILL have not received the replacement milk. They did indeed collect 3 litres and instructed me to discard the other 3. I mistakenly assumed that they would deliver the replacements at the same time as collection, but this did not occur. I have since contacted the customer care and enquired as to when I can expect the replacement, but they do not even bother to respond.
