Very very unfair

I made payment yesterday for a booking for the 3rd of January. I just send them a message now informing them I can't make it for the day due to a funeral I have to attend. I'm requesting that they refund the money and they telling they don't do refunds but they never mentioned any of this in their information guide that they send me. They say I can reschedule within the next 90 days. From the 6th of January I will not be out of gauteng for 6 months. So what is going to happen to my money? This is really unfair.
