iTunes Store in India

The itunes store is not accpeting my UCO Bank Debit VISA card that has netbanking enabled. I purchased some credit from airtel website, so the online banking thing works but in itunes it doesnt accept it.

I get a 'Your payment method was declined. Please enter valid payment method information'.

If I put in a wrong sercurity code I get 'Please enter valid security code'. So when I put in the wrong info & right info its able to defferentiate but am still stuck with 'Your payment method was declined.....

Any help please? Maybe someone else has had problems with their Indian Debit Cards, or maybe none of them work :/

Can I get someone to tell me the cards they use to get itunes working in India?

Very frustrating stuff :/
