SmallPDF Charged $108 After Cancellation—I Demand a Full Refund

I purchased SmallPDF to try it out, but I canceled my subscription today. Despite this, they still charged me $108! This is completely unacceptable, and I refuse to accept this unauthorized transaction.

How can a company continue charging customers after they cancel? I followed the proper cancellation steps, yet my money was still taken without my consent.

I demand an immediate refund, and SmallPDF needs to fix their billing system to prevent this from happening to other users. This is unfair and deceptive, and I expect a prompt resolution. Return my money now!
