Such a great company
Such a great company. I will use PDFfiller in the future. My company overlooked our Subscription yearly fee which was our fault. I contacted PDFfiller support, Ryan, and explained our oversight. Without questioning he offered to refund our yearly Subscription, which he did, knowing we made a mistake. We received a confirmation refund email 2 minutes after Ryan connected with me. I will always do business with companies of integrity like PDFfiller. Well done
