It is great it previews the bottom of the page. But, when I print it out it doesn't print out what it had showed at the bottom of my page in the preview before I printed it out.

USCG application form, cancellation. I used pdfFiller to downloand an complete an application. It was seamless, and worked as expected. More importantly, I realized I had little use for this app on a longterm basis.I cancelled (incompletely, it turns out) my trial subscription online.A month later I received notice that my 1 year subscription had been processed.Fortunately two of the technicians came to my assistance, on a Sunday, no less.They cancelled my subscription and confirmed the action with me.I was very impressed with their response, and commend the company for which they work!

I like the service and have been using for awhile! I like the service and have been using for awhile. Their customer care team was really responsive through instant chat. Couldn't get a phone number for their customer service however I believe the chat service is all you need to get assistance! Kara was the representative I spoke with and she immediately understood my situation and helped me get the problems addressed with step by step processes and links. At the end she even saved me some money with the steps we took to save my old account! Definitely recommend their service and also contacting them with any question!
