Amazon India — Refund amount didn't receive yet.

Address:

Amazon India

I ordered a product from Amazon on 17 January 2023 but due to some reason I cancelled it after some time on same day but i didn't get my refund i asked to Amazon they said they have initiated my refund amount 2130/- on 21 January 2023. Thereafter i contacted with Amazon customer care they provided me a reference number and says go to your SBI Bank. I go to Bank, mailed them and complained there they have raised charge back request but from Amazon side it was declined. Still i didn't get my refund. What should i do now
