Customer Service Online messaging rep..
I got ahold of customer service messaging system and told them my issue. Within 5 minutes I had someone already solving my issue and refunding me. The fact that their customer service was so on point with having no way to call. Actually impressed me. Thank you guys. You have my recommendation.

Excellent product did not think I really needed it at first but am very happy I got the one year subscription this has been an amazing tool for my business
Good value for price
When using the offer for roughly 40€ per year, PDF filler is a no-brainer when you need to fill in several forms a year for your household / family (e.g. insurances, real estate, etc.)
Initially I had problems being unable…
Initially I had problems being unable to access the latest addition of the forms that I needed. I finally succeeded with help guidance from the system.
CUSTOMER SERVICE THE WAY IT SHOULD BE!!
I was using pdfFiller to edit divorce documents I downloaded from the Court Clerks website. Being able to edit these documents was going to save me around $500 in attorney fees. When it was time to save and print I was directed to purchase the subscription. There are 2 options... you can pay for the whole year at once (paying $8 per month) or you can pay $20 per month and be billed each month. I accidentally authorized the whole year @$96 to be charged to my debit card. This was not my intention but I knew it was going to be such a hassle to get them to refund my money that had already cleared only to spend $20 with them. I contacted support thru the chat option anyway and found I was very wrong in my assumption. I was connected to Ray who in less than 5 minutes had refunded the difference of $76 back to my card and was inquiring if there was anything else I needed help with. This is how customer service should be and very rarely do I experience anyone who should bear the title of a customer service representative. THANK YOU RAY FOR YOUR HELP AND PDFFILLER FOR HIRING COMPETANT ENJOYABLE PEOPLE TO DEAL WITH YOUR CUSTOMERS.
New to this software but appears to be want I needed working with the many aspects of PDF's for our website. PDF Filler offered an excellent annual rate. I am concerned a little about getting to involved with them. You see it happen often after one year with service providers the rates start increasing. Than you need to find a new service to merge your existing business with. We'll see. Overall though the company has been excellent.
