MoboReader Klarna Unauthorized Subscription Charges - Refund Request

I have an active Moboreader subscription that is being charged through Klarna, and I am facing unacceptable charges and repeated payment attempts. A payment of 6.99 USD was successfully taken on 5 August, and then there were further attempts to recharge me again, which I did not accept and do not understand why they are happening. Despite my attempts to cancel this subscription both through Moboreader and via Klarna, the subscription still appears in my Klarna account and payment attempts keep being made. I do not understand the reason for these ongoing charges and find this situation unfair. I request that my Moboreader subscription be cancelled immediately and that the 6.99 USD payment taken on 5 August be refunded to me. I also ask that any further payment attempts through Klarna be stopped so that I am not charged again in the future.
