What Muay Thai gyms in Bangkok or Pattaya offer DTV packages with a money-back guarantee if the visa is rejected?

Hi everyone,

I’m planning to apply for the DTV (Destination Thailand Visa) on my own soon. My plan is to do it through a Muay Thai course.

Could anyone recommend gym options in either Bangkok or Pattaya that offer official DTV packages (specifically 9 or 12 months) and provide a money-back guarantee if the visa gets rejected?

I'm a bit anxious about the whole process. Even though I easily meet the financial requirements ($500k THB) and everything should technically go smoothly, I’m still terrified of getting rejected. My biggest fear is paying for an expensive long-term course upfront and then getting stuck with the costs if the embassy says no.

Thanks in advance for your help!
