I used PDFSmart.com for less than an hour to try compress a single PDF file paying £1.99 for the service. However, without my knowledge or explicit consent, PDFSmart charged me £49.99 for a monthly subscription I never agreed to purchase. When I demanded immediate cancellation and refund, their support team claimed they "cannot find any subscriptions" despite processing payment from my account-a transparently evasive response designed to frustrate legitimate complaints. PDFSmart operates through deliberate deception: their website uses hidden subscription terms and a deliberately obstructive cancellation process to trap unsuspecting customers into unwanted recurring charges. This predatory business model exploits consumers who believe they are simply using a one-time service.
