I, like an idiot, checked if edreams was legit only straight after making ym first purchase and not before, and saw people on reddit saying it isn't. Can anyone clarify what issue might be or if/how i can cancel?

I purchased a trip from malaga to stansted on the 14th May for £11, as I just assumed this was like Skyscanner and like a moron didnt think early enough that there was no good reason for the 12£ savings there was compared to ryanair. Everything else appeared normal and even though I wasnt sure how it worked it was so cheap i thought even if it went wrong itd be fine, but i didnt consider that it could smoehow add extra charges to my account, which people are saying. I booked the cheapest version whicih it mentioned was non cancellable. Is there any hope or way of getting that 11£ back? If not, how risky is it for me to just keep it like this and not book a second legit ticket? I have recieved confirmation emails from edreams and can see my flight ticket on ryanair website officially, so it is as of now a valid flight ticket, but i dont see any option to cancel. I will make sure to cancel edreams prime now, which says it will charge me 100 pounds after 15 days, but i should be able to cancel that before it renews. Also wehn i paid the 11£ i had to confirm separately through my banking app, so i thought that would stop any extra fees being added on by asking for confirmation for those as well, although i am assuming from what people say that is unlikely. In general does anyone have any advice for what i should do next?

Edit: I have now cancelled edreams prime, so I see no reason i should get charged any more for any reason, is there anything i need to do with my bank to ensure this?
