arpat123:Unfortunately for me, E-ON told me that I had subscribed to Internet Service and hence they sent some reminders to my email address and that is why they did not ask for my forwarding address.

This will make a difference regarding your complaint.

As you have registered to manage your account online, it says when you register that you will no longer receive paper bills through the post, along with the terms of having an online account.

This means that we will not have needed your forwarding address, as your final bill will have been available to view online, you will have received emails to advise you that he bill was ready along with reminders.

Because of this, I would say the bills does need to be paid as E.ON have tried to contact you by the method that you agreed to.
