Amazon India — account in hold and my refund is blocked

Address:

431605

My Amazon account is blocked from 5 days but they are not helping me. They said me that you will receive email regarding this issue but until I have not received any email and they are saying that your issue is your card details are wrong but I have not used any card to buy anything from Amazon just the card is is saved on it. My refund is blocked because they have holded my account it without any reason.
Also if there is any issue then why they are pending my refund I am not able to get my refund I need that money for other work I have tried all things that they said but they are not what an unholding my account.
I need my money back but Amazon is saying that the specialist team will contact you but the email is not arriving and only if they verify my details then only they will unhold my account but my refund is is still pending so they should understand that first of all the should give my refund back but they are only saying our specialist team will help me and are not helping me as they have to help me
