eDreams Prime Subscription Charged Without Consent or Approval

I bought a flight ticket via eDreams for 18 July 2026. Although I only wanted to purchase the ticket, eDreams charged me 14.99 Singapore dollars this morning for a Prime membership that I did not knowingly request or approve. A similar deduction was also made previously when I bought a ticket on eDreams, but I do not remember the exact date. This 14.99 SGD was charged to my Standard Chartered card. I do not want the Prime membership and I do not accept these extra deductions, because I only intended to pay for my flight ticket. I request that the 14.99 SGD charged today, as well as any previous Prime membership fees taken without my clear consent, be fully refunded to my Standard Chartered card and that any Prime membership on my account be cancelled so that no further amounts are deducted.
