short term loan companies say they don't have to follow ohio law, only delaware where the loan is

Help, I have several payday loans. Most have been reasonable and setting up payment plans.. however payday 1 and first bank of delaware are operated by Think Cash and are short term loans... they told me they do not have to follow OHIO laws,, only Delaware law where they are located. I argued w/ them... because they want to charge me interest everyday on the loan and first bank of delaware took a payment i should have made, and tacked it to the end of the loan,, so instead of owing the 700,, they have taken a payment and tacked it to the end and say i owe 961.00 the loan was due 26 days ago... I don't know who is correct,, ohio attorney general office told me they don't regulate the ONLINE loans,,, they are not a brick and mortar... and NO one regulates the online loans,, and furthermore, she said she had never heard the law that if they are illegal in your state then you only owe the amount you borrow... what do i do about them saying they only have to follow Deleware law.
