PDFAid And PDF-BILLING.COM Unauthorized Recurring Billing

I subscribed to PDFAid and later decided to cancel, so I ended my subscription on 26 May 2026. Despite this cancellation, I have continued to be billed every month via PDF-BILLING.COM, with charges appearing on my account in May, June and July 2026. These charges were made to my company card, which I am using while living in Singapore. After noticing these unexpected payments, I contacted PDFAid to clarify the situation. They denied being linked to PDF-BILLING.COM, even though the charges clearly started after and in connection with my use of their service. I have email correspondence from the PDFAid billing team, addressed to me personally as Ruel Ramiscal Jr., where they state that they are not associated with PDF-BILLING.COM. At this point, I am paying monthly for a service that I have already cancelled and that no company is taking responsibility for. I request that the recurring payments through PDF-BILLING.COM be stopped immediately so that no further amounts are taken from my company card. In addition, I am asking for a full refund of all charges that were taken after my cancellation on 26 May 2026, and for a clear written explanation of why these charges were made despite the cancellation.
