If you log on to your PN account in Member Cetre and click on Manage Account, then Account Summary, you'll see the date your service started listed in the left hand column.
Do you want to leave PN? Do you not want to have an internet service at all? Or are you thinking of moving to another provider?
If you no longer wish to have any internet service, you need to cancel with PN (I think they require two weeks notice) and charge a small cancellation fee (also listed in your account summary). If you want to move to another provider, sign up with that provider 14 days before your PN contract ends and your switch-over should be on the day your contract ends although this may not always be the case. If you are happy with PN's service but just don't fancy paying the out-of-contract price, contact customer options and they might be able to offer you a competitive deal for a new contract.
Bearing in mind PN's ancient billing system you may find that they'll still bill you for the month after you have left. If that happens, one of the staff who post on this forum will help you get a refund.
