Dear Laura thank you for your comment.
We sometimes join the groups together with Adventure rafting (and the other way around) - in the same situations like on that day when you had booked and your booking was the only one that we had. We join groups together to make the rafting more interesting - with more people on the boat - not just 2. On that day we had some miscommunication with the driver who was waiting at the wrong address (Želežniška cesta 6 instead of Želeška cesta 6) meaning that we did not actually forget you. I know that this does not change the bad experience that you had to go through, and we are not trying to put the blame on somebody else, just trying to explain what actually happened. People make mistakes, and after you texted you were picked up in approximately 15 minutes and you went rafting with the group that you were supposed to go rafting with in the first place. That kind of mistakes happen very rarely and I am very sorry that it happened to you. I am also glad that (from what I heard) you enjoyed the rafting and that your day and your plans were not ruined.
Thank you and have a nice day,
