Took me a while to figure out how to…
Took me a while to figure out how to delete an entire page. My one suggestion would be to leave the previously used tool activated. I get tired of having to click on "eraser" when I'm trying to erase multiple blotches on a scanned article.
Excellent customer service!
I used the pdfFiller when I had no access to a printer- it was efficient and easy to use. However this was a one off and thought I had cancelled my subscription. When I saw I was being charged I was concerned as I have no need for the service on a subscription, however I contacted pdfFiller customer services explaining my situation and I received a very reassuring reply from Max and the pending transaction was cancelled immediately. If I ever need the service again I wouldn’t hesitate to use pdfFiller or recommend them. Outstanding customer service.
