Thanks Dave, but, "as you are perhaps (probably?) the whistleblower" to Ineos, please tell them to be honest and clear.
In the past, on the Belgian Railways, when you were sitting in a train who had to stop for an (for the crew) unknown reason, they didn't communicate anything to the passengers as long as they had no information. One I sat on a train for more than an hour, and then suddenly the train continued it's trip! Very frustrating!
Now at least, they tell us: "we have to stop for a red light and we don't know why". That's better than nothing.
But I can't believe Ineos can't give an explanation, even if the delays are their own fault. Most "humans" accept mistakes. They don't accept silence, lies, blaming the other, ...
