The support team are the BEST!
The support team are the BEST!I didn’t understand that I was signing up a yearly subscription. I wanted to use the pdf only once. I notice in my account they charge me for a yearly subscription. I contacted the support group, explained my problem within minutes they solved my problem and refund my money.Thanks again for a Great job!!
Been incredibly helpful and ultra convenient.  I recommend it to everyone The lists of documents is very beneficial and highly informative
It got the immediate job done but there were a few hiccups. I don't particularly like their way text is displayed in the larger fill-in fields. The form I was filling out was very complicated and required numerous references to a "Remarks" section at the end of the form because there was insufficient space with the numbered questions to put complete answers without overwriting onto the next numbered question. Consequently, the Remarks section was filled necessitating a separate attachment to contain all the remarks. In the remarks section, I cross-referenced to the numbered question for clarity, e.g. "Question 12(b)..." When I viewed the form on the screen the formatting looked fine but when it printed, the "Q" in the word Question was on one line and everything else "question 12(b) was on the next line. I would like to know how to avoid that issue in the future.
Phenomenal customer support.
I use pdf filler occasionally for signing docs, I recently had an issue with the website and dreaded contacting Cust support-and when I finally did it was by far the easiest, quickest interaction I've ever had with a cust support rep.Dee was polite, efficient, and knowledgeable. I was stunned, and impressed-thank you Dee
