As often happens in these cases, the company has gone into liquidation. I wish ICO well in recovering the money, but they'll have huge problems and I doubt that they will be successful.
Whilst they can prevent the owners becoming directors in the future, they seem to get round it by appointing their family next time around so I have no great hopes of this being much of a deterrent. I wonder how much business 100 million calls originated. There must be enough to justify that volume of traffic. Someone on the radio this morning it could be as little as 2,000 which is a minute percentage, but presumably profitable.
