State Bank Of India [SBI] — Money refund confirmation by Amazon, but not visible in my SBI bank account.

Dear sir,

I have ordered MERLAYN Ayurveda Bhringraj and Amla Jadibuti Hair Oil on
22 August, 2023 from Amazon.
My order was then cancelled and rupees 108 refund was initiated on the same day through debit card. But till now, at the Time of writing, 4 September, 2023, no money is refunded in my bank account.

Nobody is helping me, I am very poor and this money is urgently required.

I have visited bank branch, I have talked to customer care of both SBI and Amazon.
But no solution is provided by anyone. It's very painful to visit SBI branch everyday as no solution was given to me.

The refund Id reference number (RRN) that was given by Amazon is
30005432363234207147979. Amazon claim that since RRN number is generated then they must have initiated the same money refund to my bank account.

I need my rupees 108 back as soon as possible in my bank account.

Please help me
