Dear Sir/Madam, We thank you for your feedback and please accept our apology for the inconvenience caused. We always have drivers available 24 hours in Samui to fit the demand, however the reason you did not get a driver may be because you were in an area where we are unable to go in and pick you up such as the airport. We really have to apologize for this issue. The safety of our customer is our priority so we do not want to have any trouble with other providers. The price estimate given is a +-10% of the actual price. We try to maintain our competitiveness in this area and our pricing is always the same 24 hours. We have to apologize once again for the problems you experienced and hope we can provide our service to you in the future. Thank you.
