The processing seems to have worked out fine though. If any more images were uploaded that were taken out over the water they likely would have failed anyway.
You can cancel out of the upload process at any time by leaving that page.
You cannot delete jobs that are still processing.
Since this was the trial so you can learn your way around the system and almost all the points were used anyway it doesn't make much sense to provide a refund. If you wish to do more free processing you can do it with less than 250 points worth of imagery. For further processing of larger areas you would have to pay for points.
