So I don't think there's any need to hide content for this. I'm going to be straight forward.. I keep seeing and hearing about companies rebilling... The only way they can do that is if you don't cancel that card or block ANY outgoing payments to that company (IE: you would need to call you bank or cc to block any payments going to the company you are scared will rebill).. might cost you a small fee from your bank to block companies. So easiest way is to report your card lost so they will issue you a new one.
Now if the companies don't have your billing info. Honestly, they can't do shit to you. Not to mention they don't have your SSN so it can't go on your credit or come after you with collections...
Lastly if you are a kid doing this and live with your parents and you're scared they will be sending you letters to attempt and collect money.. Then I say stay away from using your real info... But if you have your own spot then it really don't matter if they send you those letters. Just toss them in the trash.
