Amazon / Twitch Prime Help

A few months ago I signed up for the 7 day twitch/amazon prime trial to get the free fortnite skins as many did the same. During that 7 days, I also signed up for this deal which is a 6 month trial of amazon prime video and immediately cancelled the auto renewal on the french website. For some reason I've been getting charged $2.99USD a month for 3 months now. At first I thought it might of been the original 7 day trial which I might of forgotten to cancel. However there's no way for me to check as whenever I go to the prime video website, it automatically redirects me to the french website, where it shows my 6 month trial. I'm not even sure if that's why I'm getting charged or not. Is there something I missed?
Would greatly appreciate any help
