For those who want to apply for a DTV visa, my friend applied through a Muay Thai gym in Chiang Mai, since you have to register for a course at a gym before applying. He then flew to another country to submit the DTV visa application at the Thai embassy, but it was rejected. This Muay Thai gym is popular in this group , which is why he trusted it. I called the owner in Chiang Mai to ask for a refund, and she asked where I was. When I told her I was in Bangkok, she said that since she’s in Chiang Mai and I’m in Bangkok, I can’t do anything to her. So be careful, you might be the next unlucky one. The gym even threatened me if I left any bad reviews on Google Maps. The gym has great reviews for visas and advertises a refund policy, but when he asked for a refund, they refused. And that’s the reason why they have good reviews, because of Thailand’s defamation laws.
