I signed up for a subscription but only needed it for one document. I canceled but was charged again a month later. I canceled again and contacted customer service. They said the first cancellation must not have completed but refunded me the money. That is great customer service. I will definitely use them again.

Works Perfectly!
I don't typically need a lot of editing, but what I do need this service does perfectly. No guessing about what you need to do like with some other apps, and although I do sort of enjoy the uncertainty of wondering whether things will actually edit or not pdfFiller has definitely helped me be more productive.
