Sorry Gemma i dont know, but if there's a Brit bar there Im sure you could talk to the guy and he could direct you to transport details to the Malaysian border 😁😁
Ok, you came into Thailand on a 60 day tourist visa and you are going to extend that by 30 days at immigration for 1900bt, after that you could go to the mainland and get a bus down to Malasia and border bounce, meaning to get into Malaysia and come straight back into Thailand and you will get a 30 day visa exempt stamp in your passports. Also you can extend the visa exempt for another 30 days at immigration.
