Amazon India — blocked account

Address:

Gorakhpur, Uttar Pradesh

Hello,
My amazon account is blocked because i mistakenly typed wrong credit card details.
I have contacted amazon customer service at least 40 times but they are not responding well. They asked me some details which actually i can't give because i don't have that details. How could i gave them such details which i don't have?
I have also contacted through email but same thing.
Its like i am catched in a vicious cycle of email, call &chat of same thing to different customer executive. Address verification always want same details which i gave them at least 50-55 times.

I have also some money in my amazon pay balance. Which i unable to use because my account is locked.

Hope from here i will get some relief and help.
