Stoic and unreasonable

I find Intercape extremely unreasonable and stoic in their approach to doing business. I booked a ticket two hours ago. I called straight after because I realised I made a mistake and was told that I was caller number 17 and had less than 15 minutes before I needed to attend an urgent meeting at work, so I hung up. Directly after my meeting I called to cancel and was told that if only I called within 1 hour of making the booking I would have qualified for a full refund, and that these extra minutes makes me have to pay cancellation charges to the tune of 25%. This is very unreasonable and I would like this taken up as a loyal customer.
