I felt misled at first feeling I needed to purchase the pdf filler after I had already used it. The customer support team replied quickly and resolved my issue.

very amazing and interesting web as well as very useful and has a lot of options to be used. I recommend everyone to try it especially those people who they need to edit their pdf files but the one disadvantage i found is the high cost.

I needed on copy of a form, that is all and I was charged 120.00, that is an expensive copy. I have cancelled your service and would appreciate a full refund. Charge me for one copy fine, but not 120.00. Thank you

It was a little tough figuring it out at first, but it seems to be doing exactly what I want it to do. In the sending and returning process, I think it could be done with perhaps fewer steps

Customer service is A1!
Wow! Customer service is A1!I needed to fill out some forms for an outfit, a one-time thing, and signed up for the trial month.Later in the month I tried to cancel the trial period before my credit card was charged the $20, but I forgot which email account I'd used to sign up, so I was unable to log in to my PDFfiller account.Today, when I received the email saying my credit card was charged the $20, I was able to contact PDFfiller since I now knew which account I'd used. I contacted them via "Contact Support" in their website and explained my situation. OMG! When it said I should receive an email in 20 minutes or less, I was thinking, "Yeah, right!" but it was literally only minutes before I received an email saying they would be glad to cancel the subscription and refund my money.If I ever need this type of service on a more regular basis, I will definitely be signing up with this company!

I've been very happy with this product! It has helped me tremendously file insurance claims and do work since my husband has been in the hospital since 5/30/20. I did the free trial but will be purchasing it for the year.
