Incorrect billing info

Hello!

I am unable to subscribe to Adobe's products using student discounts 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 5 times now, using different IDs 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 and order by phone. Call 1800 102 5567."

I have tried to make a payment on May 21, without success. I checked my payment details and I can see that the payment is being registered at my bank but the sum is not authorized (confirmed) on Adobe's end. Also, I have spoken with customer care at Adobe, explaining what the problem is. I've been redirected from Department to Department without any proper solution being offered.

I would very much like to buy a subscription for Adobe all apps, so please someone help me!
