While I am sorry that you missed your flight, but the rules are very clear, you need to understand if they had allowed you to board the flight could have been delayed, as it may have been parked far away from the terminal ( which is what the supervisor may have gone to check , when he left you) . They do try to help you IF , they can , but not at the cost of a delay, which they will be pulled up for and is not fair to passenegers who came on time. You must reach the check in counter latest 1 hour before departure , not the airport or the check in line, but the counter. Roads are being dug up, traffic jams etc - plan for these diversions . your ticket was a promotional, dont expect to get a refund at the bottom level, speak to the mangement , maybe they will help , if they can.
Next time , stick with a travel agent they give you a lot more information, may cost a bit more , but its worth it.
