Amazon India — Blocking account without any intimation and not refunding voucher worth 5000

Address: Bangalore

I had purchased a shopping voucher of Rs.5000 from Amazon; when I try to redeem it my orders were getting auto cancelled by the Amazon team.This issue started when I raised a complaint through ingram via Grievance Number: 3808355.After forced to give refund back to me in the case(since it was Amazon's mistake) they blocked my account which I got to know when my orders were getting auto cancelled.There was a lot of communication with the team regarding this and on 29.12.23 they confirmed that the order cancellations was a mistake from my their part and I can continue to use my account(Document 1 attached) On the basis of that only I bought a shopping voucher and when I try to redeem it, orders started getting auto cancelled again.When contacting the customer care team, they are simply stating since they found some issues in my account, they have cancelled the order and arrogantly state that "We'll no longer be able to intervene on this subject and your emails will remain unanswered."(Document 2 attached) My request is to cancel the shopping voucher and refund the money in my original payment method ASAP.
