Inability to assist with ********** transaction

For the past few months, I have noticed an unknown debit order on my Bluebean account. It indicates [URL Removed] Every month an amount is debited to my Bluebean card for something that I have no knowledge of. Upon further investigation, I contacted Tzarmedia and receive the same message. They have no record of me or any transaction. It appears to be a ****. I approached Bluebean ***** and customer services and received no joy. I was asked to complete a form, which I did. Subsequently I was informed that it was not a ********** activity and that customer services has to deal with it. Customer services tell me that they cannot stop the debit order. In the meanwhile, I have an amount debited to my account monthly for which I receive nothing. I cannot give the bank a fixed amount as the amount varies from month-to-month. This is obviously linked to an exchange rate. If I can work that out, surely banking officials can to? I am at a dead end. What do I do?
