Andrei I am going to start by quoting a customer from the very same trip as you....
"Harry provided so many facts, information along with humour he was simply a perfect host. The crew (I think Nat and An) kept us to schedule and safe throughout constantly on hand helping us all on and off the boat. We did have an engine hiccup very close to harbour, on the way back, however this was not an issue as we felt well informed, safe and were back on our way in no more than 15 minutes later. This was a plus as we were all able to watch monkeys on the shore by the mangroves finding food, washing it and eating! Do not hesitate to book, you will be talking about your experience for years to come."
Based on your account we have some major differences of how the day panned out.
Our team were approached by multiple couples on your tour that went out of their way to let our team know that Harry and the crew performed over and above their expectations despite the clash between yourself and Harry.
My first comment is that Harry is not Superhuman... when prodded and poked enough, even he as our most senior and respected tour guide is also susceptible of letting his excellent customer service standards drop under duress of harassment by an 'all knowing' customer.
This trip did suffer a break down, which was a completely routine event. Propellor boot/splines do fail and there are no idications as to when this will happen. The crew elected to continue on one engine towards the pier and soon afterwards the crew needed to switch over the fuel lines from one tank to the other as an imbalance of fuel had developed between the port and starboard side through operating on one engine.
I stand by our crews decisions as the correct course of action, and there were no alarms related to any pending failures as seen in our diagnostic tools.
Had we followed your suggestion of disembarking in the middle of a tidal mangrove forest amongst troops of potentially rabid monkeys, poisonous snakes etc... who knows how the day may have panned out? My crew are sensible enough to follow their own course of actions with their decades of experience guiding them, even when their customers appear to have all the answers, without any practical knowledge of the situation at hand.
Your lack of understanding of the situation is understandable, however your suggested remedies and course of actions are just nonsense. It's a real shame you feel the need to bring down a company that works tirelessly on producing the best quality tours we possibly can, with the highest standards in operations and maintenence in Phuket.
Your refund has been processed, I've reviewed the course of events with Harry and the crew, and as always we take away some ideas of how we can handle these types of events better going forward.
Safe travels.
