why wont my debit card work on itunes? its saying my security code is wrong and then a message saying contact apple support??? Help please

Not all debit cards still seem to be accepted, and they may not be accepted at all in some countries. For the security code error try : iTunes Store: My credit card's security code or zip code does not match my bank's records - Apple Support

If you still get the message to contact iTunes Support (these are user-to-user forums) :

- go to http://www.apple.com/support/itunes/ww

- click on your country's flag

- click on the Contact Support at the bottom of the left-hand column

- click on Contact iTunes Store Support on the right-hand side of the page
