For whatever reasons, the "None" option is not always available to all users and I think it may be related to what country you live in. Short of contacting Apple to get it straightened out, if you haven't done anything with your new ID ye - you can create an Apple ID without a credit card and simply abandon the one that you just created.
This explains how you can creaet an ID without a credit card.

The two big things that you have to remember for this to work are ... you have to sign out of your existing Apple ID .... Settings>Store>Apple ID - tap the ID and sign out. Then you have to try to download a free app to bring up the window that asks you to sign in or create an ID. Read the information on the website that I referenced above.
If you have not used the original Apple ID for anything yet, you can simply ignore it and use the new one - or like I said earlier - contact iTunes support and ask them to help you sort it out.
Here is a link to iTunes support. You can change the country in the bottom right corner of the screen.
