State Bank Of India [SBI] — refund from amazon not received yet

Address:

400709

I have ordered honor band 3 from amazon but i didn't liked it, so we have returned it to amazon and applied for refund from amazon.
Amazon has issued my refund on 11th oct 2019 but i still not received that refund from amazon. My bank balance not got updated and i checked my passbook entries also but there is no entry of amazon refund. I called to amazon for this issue they said that they have issued it please call your bank and ask about transaction details after that i called my bank but they also said they can't do anything about this issue.
Please solve my this issue
