Refund For Unwanted Payment - iDrama

I have a serious problem with my iDrama subscription and the unauthorized payments taken from my card. I initially used a weekly plan with iDrama, but within the last two weeks there have been automatic deductions from my card without any clear information or consent. Today, a yearly plan was activated even though I did not intend to subscribe to a yearly plan at all, and money was taken from my card. When I enter my account, I cannot properly manage or cancel the subscription and I only see that my money is being taken. I do not see a clear option that allows me to cancel, and I am not given sufficient information before these payments are processed. I request that all iDrama subscriptions linked to my account be completely cancelled and that every payment taken from my card by iDrama, including the yearly and weekly plans, be fully refunded. I also ask that I am given a clear and easy way to manage and cancel any future subscriptions so that no more unwanted deductions are made from my card.
