Over 4 hrs delay

Hi , My journey into work took over four hours and I will be losing half a day's work being an contractor . I know I am entitiled to an refund which will be around 11 pounds as I am a season ticket holder. Who will compensate me for the loss of work . We were not even given water on train or even after we got down. This is the second time its hapenning, do you guys intend to do anything about this . How long should we be suffering like this?
