Internet lenders must be licensed in your state if payday loans are allowed. They have to conduct their business legally before throwing any actions against you.
I haven't heard of any internet loan company especially those not licensed, filing a case against the borrower. If they give you such threats, don't be bothered. It's a crap. If you have the loan from them, you are responsible to pay the borrowed amount and the fees mentioned in your state.
