Successful Chat Support
Kara helped me locate a document that I could not find after downloading it. What a relief!
I was extremely worried because personal information was on the document. Through the chat support feature, Kara guided me in locating the document in my account (which I didn't know I had), moving it to the Trash, and then permanently deleting it.
The system was quite user-friendly, however the quality of the initial edited documents was poor, with a green tinge appearing behind the altered text. A note to Paul at customer service had a solution identified, which solved the problem.
My account was charged after my trial had expired. **************** was prompt to help me. I will definitely use pdfFiller in the future.
