Amazon India — account blocked and no adequate response

Address:	302, Progressives Solitaire, Sector - 11, Koparkhairane, 400709
Website:	amazon.in

On 24/2/19 my amazon buyer account was blocked stating that my use of the payment card supplied was not authorized by the cardholder. Which is not possible. I am the card holder. I don't know who they are talking to. Incidentally my old debit card was blocked as the bank automatically issued a new debit card. Now I think because of this action from the bank my previous registered debit card caused the problem. Having communicated the problem to the amazon social media team, consumer team and account specialist, there has been no adequate response from the team. There has been a misunderstanding from the amazon team and they are not helping me to resolve the issue. I am a member of amazon prime, with audible subscription and kindle purchases. Despite being an ethical loyal customer, i have been treated with willing negligence.
