Payment not getting authorised by adobe

I am unable to subscribe for Adobe's products because my payment is not being accepted by Adobe.

There is only one method to pay in my country (India) and it is through credit or debit card.

I tried more than 10 times now, using different cards with even different Banks but every time I get the same error:

"Incorrect billing info

We are unable to approve your transaction at this time.

There are a number of reasons for order failure, among them errors in the payment information, or billing address, or an inaccurate email address. If you have verified your information and are still unable to place your order, please contact Customer Service." But i got a message from my bank that the transaction is successful. Pls help
