Hello, I need to communicate with the customer service of IMDb .I want to contact with you. There's been a misunderstanding

Dear sir or madam, I have never registered in IMDb. As you can see I have never used this account until today because yesterday you withdraw money from my card without my permission and I wanted to see what going on. I signed in once by my amazon account to see your page but I wasn't interested at all and never used it. My bank has sent you a transaction dispute.I never agreed on this freemonth you offered and surely never give you the permission for this IMDbPro whatever. Please inform me what o should do to take my money back.
