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

This he first time that I have really used this program nd it has taken me a little while to get used to filling in the forms. Overall it has been fine

I use it for filling out work related forms. The forms look much better when filled out online rather than writing in all of the data. I'm able to save a copy online or on my computer, rather than filing a hard copy. It's very convenient and the forms look good too.

Awesome!! I don't know what I have done without you. I do real estate transactions weekly and I love that I can upload different documents, edit them, and send them out. Well worth the cost. Thank you.

PDFfiller is a GREAT program with INCREDIBLE customer service!
PDFfiller is a GREAT program! It is very easy to use. It helped me tremendously when I had a project and needed to fill out literally hundreds of documents online. The program worked very well, was incredibly responsive, & even kept all of my documents for easy access as well. Most importantly, however, is that they have absolutely INCREDIBLE customer service! I used the chat feature and it was totally painless and even enjoyable. I was treated very well by the chat rep (Paul)! I am a single mother who is trying to start a small business with VERY limited funds. I meant to cancel my plan before my 30-day trial was over. Like so many other times in my hectic life, I guess I forgot! I was quite anxious about it as many companies charge high cancelation fees if you fail to cancel during the trial. There was no need to worry though. I simply logged into my account and then I saw the chat feature. I chose to use it even though I was hesitant to do so (many companies do not provide very good customer service through chat). The response time was extremely fast. I asked to cancel my membership and he replied right away that he would do that for me. Here is the best part, he then proceeded to ASK me if I would like a refund as well!! Now that is WONDERFUL CUSTOMER SERVICE!! Thanks so much, PDFfiller & Paul! I will definitely use them in the future and recommend them to my family and friends. You just do not see that level of customer care combined with great products anymore. I was quite impressed!

I love being able to use PDFfiller. It sure makes completing forms much easier and quicker than printing them and writing forms out.
Some forms are not able to be saved after filling them in. They save blank. I have to download the form and then save it to a file.

Great!
I had never made documents interactive before so I had no idea what I was doing. This was so easy to use. I really just needed it for a few documents so there was no reason to keep the subscription. If I needed it though I would not even hesitate to pay for it.
