Amazon India — Promised No Cost EMI discount was not given

Address:

Amazon India

I have bought three products 55inch Sony Bravia TV, IFB microwave and IFB washing machine during Diwali sales in 2021 from Amazon under no cost EMI sales offer. But Amazon backtracked from its promise of no cost EMI on Sony TV and IFB microwave. My order no. is #[protected] They created a ticket no. ddcfada3-519d-47d3-ade1-bffd9a6f5bd8 and referred the matter to payment team and told me there was no offer of no cost EMI on these two products.
I asked them to show me the Diwali sales page offer of these two products but they denied. This shows something fishy is there that shows my grievance is genuine.
They are denying me my rightful due and mentally harassing me and monetarily cheating and laundering me.
I hope u will coerce them and help me get my rightful due.
Warm Regards,
