I had a misunderstanding with PDFfiller . . . thought that I had cancelled my subscription immediately after discovering that it didn’t fit my needs, but something went wrong, & I was charged for a one year subscription at the end of a 30 day trial period (didn’t realize that I was in it). When I went to the Customer Assistance website & explained the problem, PDFfiller immediately refunded the amount charged. Honorable people!
