Incorrect billing

Hello. My name is Michael Premdas and i live in Geneva Switzerland. You have debitied my visa crédit card of CHF70.80 when i absolutely do not have anything to do with your company. My email adress is premdas@bluewin.ch.  Visa has told me that you have also taken the same amount last year. I urge you to refund me my money asap. Awaiting news from you.
