State Bank Of India [SBI] — amazon refund dispute

Address:

Devankit sadan, Agency mohlla ( near of jal sansthan ), Srinagar garhwal, 246174

I ordered a product in 456 from amazon on 4-5 october and pay the online payment method. But after some time i cancelled my order and request to refund from amazon. Then amazon did refund on 4-5 october which is not received me. Afterwards i contacted the customer care of sbi and amazon. But i didn't received refund. So it is my humble request. Please solve to my problem. I hope refund will be in my sbi account as soon as possible.

Thank you
