I've had problems expanding boxes to fit text in. Customer support sent a YouTube video and that was some help and fixed one box, but then I had problems with a second box and just didn't have the time to keep trying to fix the problem.
After a few attempts I was able to fix the problem, and now I am very impressed with the program.

Amazing Customer Service
While I was reviewing a couple of unauthorized charges on my PayPal account I noticed they were from PDF filler. Upon further investigation as to what PDF filler is, I realized that this was due to something a professor from a course I had taken last year had required the class to use to complete an assignment. He assured us that though we may need to put in our personal information, the service we were using would be "free". I did not realize that “free” was then turned into a renewable purchase fee. I contacted PDF filler to dispute the charges and explained what had happened. This company responded to my email with genuine kindness within a couple of hours to assist me with providing a refund upon receipt of a response providing verification information. I emailed them the information and again, within a couple of hours, I received a response that I had been refunded the fee. I appreciate how professional, considerate, and amazingly responsive this company has been- the whole process was quick and painless and I will certainly consider using PDF Filler in the future should I need such a service!!

Exceptional customer service
Kara was of great assistance working through my billing question today. She was quick to respond and went out of her way to explore all avenues before I realized that the expense about which I was inquiring was charged by another company, not pdfFiller. She was extremely polite and patient.
