Where can I get my marriage license from the USA translated and certified in Bangkok?

Quick question I went to the British Embassy and registered to prove I'm single eligible to marry a Thai woman I was told it had to be translated my wife found someone who could do it we went 24 hours we then went to the other building after a bit of a weight hanging around they came out with a Red marriage certificate book but they never seem to get me my English version back that I got from the embassy saying that I was single infant until nice arts out her visa stuff I didn't even get the married certificate as it was in Thai on both sides any advice on this ? If that's the norm would be helpful
