Just had a word with Isotek's former press officer and apparently it's true - Isotek's holding company, Spotlyte, has gone into voluntary liquidation, with the result that there is indeed no more Isotek, or Activ Disctribution, though it's possible the brand may re-emerge at a later date.
Thanks for the info, that is sad news and it seems I may owe Marc an apology if I appeared sceptical.
Marc,
I apologize if I appeared to be sarcastic or unsympathetic to your plight, but with trolls popping up recently all new posters are possible suspects especially when posting dramatic comments, my commiserations on the loss of your job.
