One of the ways to upgrade on JibberJobber is through PayPal – you can do a onetime upgrade (1/3/6/12/24 month(s), etc.), or you can do a recurring subscription.  If you do a subscription and then want to downgrade later, the steps are easy, but we can’t do it for you.  Even if you DELETE your JibberJobber account we can’t cancel the PayPal subscription for you.  There are instructions in the FAQ, and on the My Account page (when you logged-in), but I wanted to put it here also.  These are instructions I just got from a user (since the instructions Paypal has in their email is not as detailed):

1. Log into PayPal
2. Click the History sub-tab under My Account
3. Find the last subscription payment transaction in your history
4. Click the Detail link for that transaction
5. Click the S-number link at the top of detail page
6. Click the Cancel Subscription button at the bottom of the page
7. Click the Cancel Subscription button on the confirmation page
8. Click Return to Log to confirm the cancellation transaction now appears

Thanks Dieter, for putting these instructions together!
