Great system. A representative had a little bit of a short temper. I was asking questions because I really did not understand. So, I finished my chat and started a new one with someone different.

Amazing customer experience Amazing customer experience! Their services are quick and efficient. I started with their Live Support Chat but was quickly connected to staff members who responded to me by emails. I had Marie and Anna to help me. They are all friendly and extremely helpful. They responded to my question quickly, and after I explained to them briefly what my issue was, they took care of the issue swiftly. Their software is easy to use. Thank you all so much again for your help! Keep up the excellent work you do!

I wish it was a little easier to type things into my papers however I am getting the hang of it, I dont like that sometimes I will click in an area and the typing bar doesnt appear where I clicked on, but near the area, sometimes thats in the middle of a line on the page and thats annoying.

Had a fantastic experience with… Had a fantastic experience with PDFfiller with the refund I requested. I registered for a trial version and canceled the same day but they still charged me a month later. I brought that up to their attention and they promptly processed the refund. I thought they were going to give me the run around like many companies do but I was pleasantly surprised. Keep up the great customer service guys.
