pdfFiller scores top ratings on review platforms
EXCELLENT customer service! The product is really good too... I had a small issue and they responded to my contact within about 15 minutes and they gave me a free month on my account.
I had problems using this program. Customer support helped me to figure out what was causing the problem and fixed it. I appreciate their time and effort.
Good afternoon,
I have subscribed to PDFfiller and have even been charged $20 yesterday to use this program, however, when I try to log in, my password isn't recognized. Also, when I try to go back to change anything on my form, I find it time consuming to try to do this.I don't have a lot of spare time at work & I really don't like using the typewriter, because if I make a mistake & find it later.. I can't go back and change it, hence PDFfiller..
It says a msg will be sent to my email, however, I never receive this msg. It's not in my Inbox, Spam or Trash folders. I would like to use this program at work, so I don't have to use a typewriter.
Can you help me with this log-in issue?
Many thanks,
Joyce Durbin
