A friend of a friend told me about a possible glitch in your reservation system so he wanted me to know and let you know since I have your contact details.
They went on the website
http://www.samuicode.com/
and then when they went to make a booking they got this link:
https://www.thebookingbutton.com.au/properties/codedirect
They cleared the cache and closed the browser and still got the same link
https://www.thebookingbutton.com.au/properties/codedirect
Just thought you should know in case you didnt as it may affect future reservations for the upcoming busy season.
