As for the storefronts, you will need to make payment arrangements with them, they are licensed and they can take you to court to get a judgment against you. Now the internet are different, they are not licensed and this gives you room to make settlement arrangements with them. I highly suggest that you file a complaint with your AGs office against them. Then you will either need to block them from debiting your account or close and open a new account. What state are you in, it would help to know this, to give you more accurate advice in your situation, laws vary from state to state. If you have been paying roll over fees for a period of time it may be that you have already paid back the principal and legal interest rate allowed by your state and you could demand they mark your account paid in full.
