IMDb They charged me $1.00 to my credit card without my consent, no costumer service number, I emailed them and they say "Sorry" Internet

I was checking my Credit Card statement and I found $1.00 charge from IMDb {I didn't know what was IMDb} so I called my bank and they said this company charged me $1.00, I never signed up for anything, I only use this card for physical purchases {In stores} so I called them and they are very clear; they do NOT offer Costumer service - that's it, simple and easy for them. So I send them an Email asking them how did they get my information and they said;

Our records indicate that the credit card referenced in your message was used to activate an account on our site, IMDb.com. Please note: The credit card number was entered in our system but no charge was issued from us.

They were also very clear when they also said;

So I had to send them an Email again asking them for further information and they replied;

Due to security and privacy concerns, we're unable to discuss specific credit card transactions or other details directly with you; however, please rest assured that our fraud investigation department routinely cooperates with law enforcement and financial institutions on these matters; and upon request from them they will provide all information needed to investigate this matter.


... So, I had to cancel my credit card and I opened a new account. - IMDb just don't want to know anything else.
