Prime membership cancellation

I booked flights through eDreams in December and did not knowingly subscribe to any additional membership or service. Since then, I started noticing monthly deductions from my account for a subscription I did not intend to sign up for.

As soon as I became aware of the charges, I cancelled the subscription, however I am still being billed. I have also struggled to get proper assistance regarding this issue.

I find this extremely frustrating as I do not regularly use this service and did not expect ongoing charges after my booking. I have requested a refund and confirmation that the subscription has been fully cancelled.
