It seems you did not understand the product, at all. You were informed with 2 days before about the chances to spot the wildlife:
"The chances to spot them are about 70%. Do not forget that wildlife have their own way of living and we, humans, try to approach them as much as possible in their natural habitat." We offered you the option to join us, free of charge, next day. Anyhow, thank you for your feedback which helps the future tourists when they want to book the program. By the way, we had bears next days and those who accepted to join us, free of charge, were more than happy. And we had GREAT reviews from people who understood the experience.
