Koh Mook Rubber Tree Bungalows

We booked our stay 3 months ahead. When we turned up, the owner had no idea about our booking as they apparently "do not use Wotif" (we obviously booked through Wotif) and we're not due to open for the season until the next day. We then found the room that we were offered to be full of mould and what looked to be a blood stain on the pillow. Apparently during the off-season the bungalow rooves had leaked, causing extensive mould. They were then not able to offer us another room that didn't have mould (the other three they showed us did too), so we left. We have since not been provided with a refund as the owner of the accommodation is adamant that they don't have a WotIf account (even though I've shown it to him) and that it has his old phone number associated with the account. With English being his second language, he has also told Wotif to not refund us on the basis that, he believes, they have not received any money from us, so have no refund to give (even through we have paid). Throughout our interactions with him, the owner has been relatively friendly, and obviously also been confused (with English being his second language). At the end of the day, aside from the property, unfortunately, being in a very poor condition, I believe this reflects most poorly on Wotif - they should not have unverified properties listed on their site. We're still yet to get any refund, so this has naturally been a very disappointing, and costly, experience.
