I wanted to convert a PDF to Word, and the site claimed it would cost only 1 THB after linking my payment method. I agreed, thinking it was a one-time micro-charge. However, in less than three days, I was charged 339 THB without any prior notice or confirmation.I tried to request a refund, but there was no button or form to actually do it — only a message saying refunds are “available.” That’s extremely deceptive. No clear cancellation process, no support response, and no transparency.This feels like a scam disguised as a simple online service. I do not recommend anyone using toppdf.co unless you want to risk unauthorized charges.
