Hello Pepe,
We're sorry to hear you didn't have a good time. We advertise the seasons and visibility of each season on our website, Viator, Trip Advisor etc. Guests are able to book a tour w/us all year long. Some seasons will have better visibility than others. Sometimes we can have inclement weather that can play a role in what we see while on the water. It is totally possible on a cold night that you may not see anything, as nature does what is does, but to not see something while on tour is extremely rare. However , we can not guarantee nature. We do offer rain checks to guests that did not have any visibility to come back out at a future date. We have never received any phone call from your party explaining your situation. Feel free to give us a call.
There are over 1k reviews for us here that say our guests had an amazing time, so to say our experience is a "total ripoff", is not a fair statement at all.
Hope to hear from you soon!
