No Subscription But Weekly Charged

I live in the Netherlands and have been repeatedly charged by Netshort for a drama series subscription that I do not use. I initially signed up to Netshort once, but I unsubscribed afterwards through their system. Despite this, Netshort has continued to charge me 17 euros every week since 26 July. So far I have been charged 9 times in total. One of the transactions on my ABN AMRO / ICS card, dated 19-09-2026 for 17.80 euros for a digital product, is an example of these repeated charges. After noticing this situation, I contacted Netshort support and also wrote to the email address provided in their user agreement, but the charges have not stopped and I have not received a satisfactory solution. I request that all unauthorized weekly charges be fully refunded to my card, that my subscription be completely cancelled, and that any further charges to my card be stopped immediately.
