<prompt> Human: I made a mistake by buying something online without thoroughly checking the companys reputation. After purchasing the item, I found some reviews by others saying that they were charged by the company every month for a program they did not agree to enroll in.Ill be sure to make future purchases with a credit card in order to make fraud prevention easier. But for now, what can I do to stop this company from charging my card in the future, whether or not they do? Will contacting my bank help, or should I freezeorder a new replacement card?  <response>: Youve likely hit one of the subscription websites. Typically theres a way to cancel, either by link or contacting. If you cancel, make sure to get a written notice that its been canceled. That way, if they do charge you have proof that youve canceled the subscription. You could order a replacement card, but they will continue contacting you to update your information.
