1200 gone birthday ruined

I booked on the 17 for quad biking at Hakerville to celebrate my birthday on the 21st of September, paid 1200 as it was me and my patner, we drove from capetown to Knysna for the holiday, saturday in the morning, i call the admin from wildx to change the time only for them to tell me i made the booking for the 17th, i must have made a mistake during the booking. I have pleaded with the owner, they just told be about their cancellation policy, what makes me angry is they couldnt even do the courtesy of calling to confirm because the booking was made at around 11pm, that should flag that theres a mistake, or when theres a no show, send an email atleast. They were inconsiderate, they just responded by saying you didnt show up, no ride.
