[Resolved]  State Bank Of India [SBI] — Refund not credited from amazon Rs12999

I should have received my amazon refund of Rs12999 by 12th of April for the order id ORDER #[protected]. Amazon asked me to contact my bank for the refund with the Refund Reference Number.The bank didn't respond to my email for more than two weeks. I couldn't travel from Chennai to Kanniyakumari because of the covid restrictions. I was not able to contact bank through the contact number because it didn't exist and the customer support told me that they can't help me out regarding this. Then finally I got the contact number of someone who works in the bank and he finally took up the issue. But the bank replied that the given number does not pertain to SBI so I have to take up the problem with amazon. When I contacted again, amazon told me that there is nothing to be done from Amazon's side and they can't even take a complaint on that matter and I have to contact my bank for the refund.
The Refund Reference number is: RRN[protected]
