Great services with an excellent customer care policy I enjoyed great services provided by pdfFiller through an annual plan. I used their service in all my dealings with pdf documents. Then for professional reasons, I had to cancel my subscription, and pdfFiller team was extremely kind in offering me a full refund of my subscription fee. Just after 3 minutes of sending them a message, they responded back explaining the details of my refund process. That is what I call a great customer care and professionalism! Once again thanks a lot!
