Great driver, let down by company communication

Our tour guide Novak was fantastic! He ran a great private tour, with a good mix of swimming stops and sightseeing past local landmarks. He was friendly, knowledgeable, and made the day really enjoyable! Unfortunately the experience with the company itself was less smooth. The boat departed 30 minutes late. We discussed extending the return time by the same 30 minutes to make up for it, and this was agreed to, but it didn’t happen, and we ended up cut short anyway. We were given a 40 euro discount as compensation. The bigger issue was communication. We sent multiple messages through their chat before, and never received a single response. Overall, Novak was fantastic, however disappointed by the company.
