In the past this has happened to me twice, both on tightly timetabled days. I was so furious I tracked down a senior member at the Fusion HQ. On both occasions I was offered, at my request, a refund for lost useage and loss of my valuable time. Management by Fusion of the Dulwich centre has always been lamentable and I guess that unless they are penalised financially and/or they are threatened with the loss of contract renewal coming up in the near future they clearly feel that there is no incentive to run the service to customers satisfaction.
