Amazon — refund against an order

Hi sir/madam,

I bought a mobile phone on www.amazon.in on 8th oct 2019. The product cost was 11935.85. I choosed hdfc debit card emi for paying. Unluckily the product returned to the seller. As the product returned to the seller amazon initiated a refund on 10th oct 2019.
Till now i did not get the refund and debit card emi is also active as refund is not credited.

Bank is saying that no refund is issued by amazon. Bank did not find anything with reference number provided by amazon.

Reference no of refund is[protected].

Amazon order id is[protected].

I request amazon please issue a refund again. It is 11935 rs. I cant imagine that i lost my money. Please issue a refund.

Thanks and regards,
