Kara, The Support Agent
The Support Agent, Kara, that helped me with what I wanted to do was very accommodating and friendly. I had not fully explored the features of this application but I needed to get something rather urgently. Kara was very patient in explaining to me all that I needed to do. I am quite impressed with the Support provided by Kara and by PDFFiller itself.
I had to use as a one -of to sign a document, but inadvertently signed up to a subscription. The website itself wasn't too clear, so no marks there. However, once i realised i was signed up and contacted the company via email, it was resolved with 2 emails over 2 days - from *********! And with me using my son's email address and forgetting i had done so. Very happy to get a refund. ******, *********
