Good read. As for the 100 bht change they asked me if I wanted them to fill in the application for me it was a 100 so maybe if you didn't fill it in the charge was for that but they should have been clear.
well in my experience over the last few months is this. Some agencies said they couldn't help me. Obviously the more genuine ones. Others said they could but ask for a huge fee and when you ask them if it's legal they don't get back to you. One guy quoted me 75 thousand bht for a one year stamp and when I asked him he asked if I was the Police. I know one person who is in the same predicament as me got his visa and he paid 45 thousand for it but he didn't have the 800 thousand in the bank so they put it in for him. Not legal. I asked the same company and when I told them I had the 800 thousand they couldn't help me. Be careful out there that's all I'm saying.
you have to print one off in colour and two copies in black and white. If immigration ask tell them it's the original. Don't mention it was emailed to you. You have to have to two copies of everything including every page in your passport with a stamp including your last entry stamp and two current passport sized photos. Someone with also with Thai ID and confirmed address and duplicate copies and you will get an under consideration stamp. Then that will allow you another 30 days which will start from the 27th September.
