ok! Pardon me if I am wrong, thais don't speak english very well, when they say work permit they might be referring to a WP3 letter. I have seen lot of people calling both the letter and WP3 as same "WORK PERMIT". The question is why they are not letting you fix the application?, as i said everything is a headache here all the paperwork, my suggestion, look for some nice county where people understand basic english and paperwork process is not a big hassle.
