Hi,
As you didn't mention your state, it is pretty tough to assume whether or not payday loan lending is legal. You have to first find out if payday loan lending is legal in your state and if it is so, you're liable to repay both the interest rates and the principal amount. If it isn't, you will probably require paying back only the principal amount.
Now as you say that you want to consolidate your payday loans, you can certainly do so by contacting a payday loan consolidation company. Tell them about your hardship and they'll work out an alternative repayment plan with you where you have to make a single monthly payment to the company. The interest rates will also be drastically lower in order to enable you to facilitate the repayment procedure.
Hope this helps..!!!
