Online Payday loan help - Indiana

OK, so I have been asking questions and following the forums and I just want to make sure all of my ducks are in a row. I live in Indiana and I have several payday loans. I just want to make sure that these are all illegal and that I am taking the right course of action.. I have defaulted on all of them, but have been unable to send my letters because i had problems with my bank. I am finally getting the accounts closed this week and am ready to get things moving and
behind me.
