I have a bit of a problem with my visa, when I arrived in September, I got what I thought was a 3 month visa from the thai embassy in my country, but turns out it was a 3 month single entry visa, I tried to leave in December to be told I had overstayed by 22 days, I couldn't pay the fine so they wouldn't let me on the plane I've been here since, I've bought another ticket to leave on Monday, what can I expect from immigration again when I inform them I can't pay the fine? Thanks
