pdfFiller scores top ratings on review platforms
Only criticism is I tried to pay with my New Zealand AMEX and it was rejected and Amex NZ blocked the card sensing you were defrauding me! Payment went through via another card but only after the bank got my OK as it seems your company has some "black marks" and perhaps inadvertent links to some known fraudsters.

I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named Anna was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)
