PDFfiller came in very handy, especially with the ability to fax. Recently, I had to complete documents on behalf of my mother after my father passed away. I was limited because she had no internet, so I purchased a portable MIFI and once I realized that I could fax with PDFfiller, this eliminated the need to spend money on faxing & postage.

The product works I was able to fill forms and use powerful tools. They are not Adobe though and they charge nearly as much. The web sight interface was easy to use. They charge WANton much especially if you want the option to use it for only a short period of time.

I have been trying to cancel my… I have been trying to cancel my subscription for months. One of the problems is that I can't find the account. I have tried all of the email addresses that I use and can not find it. I have sent emails and wrote tickets trying to get some help but have recieved absolutely no response. I am paying $50 a month for a service I am unable to use or cancel. I was able to finally talk to someone who helped me find the email the account was under, canceled it for me and refunded the charges. The whole thing was quick and painless and I got the best possible outcome and that gives the 5 stars in my book. Thank you pdffiller for taking the time to hear my problem and helping finally find a resolution.
