Debit order on my account without my consent

That is just ridiculous. They tell me that I signed up for this and they have all my details. I have never even been on their website. I do not know who they are. And if I want to cancel, I must pay an amount to get out of the contract. I NEVER SIGNED UP WITH YOU. MY DETAILS WAS ******, *****, WE LIVE IN A COUNTRY WERE ***** IS THE FIRST LANGAUGE. <br> Stop *****ing peoples money that works hard for it.
