I wouldn't recommend this website. They reject your application for the most trivial reason and then keep your money and you can't even challenge the rejection. Much better to do all applications in Thailand face to face
And that's on the wise app! Showing you how transparent they are. But if you're happy to do it with MoneyGram for 120B saving (about 2.5 pounds) go for it!
