TWX Magazine Subscription Service charged 3 unauthorized subscriptions to my credit card newburgh, New York

My credit card was charged for 3 magazine subscriptions which I did not authorize. When I finally reached a person they refused to tell me where they got my credit number. They said I took a survey over the phone regarding a purchase I made online. Obviously the company I purchased from gave out my credit card number. Still trying to track down which company it was. Had to call my credit card company to have the charge removed only to find another one on my next statement. They said these people are using different business IDs and that's why they can't block them. While I was speaking to them they found another charge which hadn't shown up on my statement.
