Amazon India — Amazon fraud - credit card

Hi, Actually I have ordered some product worth morth 60000 Rs from amazon in recent great indian sale and there is pop up written that if we purchase from amazon they will provide a cashback of 5% for prime and 3% for non-prime I have ordered and my billing cycle has been came I received just cashback of 266 which is for the products bought by one-payment and things which I bought from EMI are not applicable for cashback .

I request the team to help me to file a case as they have cheated a lot of people like this there is no where written tat it is not applicable on EMI transacations .

I request you to help me and provide a compensation on it . They should have a big penality against this as they have violated the customers and cheated on them .
