Aliexpress.com — Regd. online payment

Address:

Indore, Madhya Pradesh

Sir/madame,
I recently got my state bank classic debit card (Mastercard) with which i am trying to make an online transaction at www.aliexpress.com.
Whenever i am initiating a transaction it is not getting processed. I get this message that there are insufficient funds in my account but this is not the case because i have sufficient funds to proceed for this payment.
Kindly see to this problem and reply for the same.
Also i would like something to be done about it.

Thankyou.
