I was on Koh Samui with <company name removed>
So I would say, unbelievable, that someone like that has a base. His car is a disaster, because the thing consists only of rust, hardly starts and then he calls it even "car with character". His hobby is the customer care and that is well. He also does not care about safety, who takes photos during the try-in dive and in the course. In the course, he even lets exercises in the open water, especially the so important repetitions When it comes to money, he always asks first, before the trip even starts and if you're lucky you get your money sometimes back, but rather rarely to not even. Dive packages are booked in advance and if you can not dive the package, then your money is still gone. I absolutely can not recommend this base as there are much better on Samui.
