Flipkart — refund not got yet.

Address:

Bangalore, Karnataka

I have purchased a shoes form flipkart on 13th september 2019, by making payment of 474 rs through indian bank debit card. Due to some reason i cancelled the order on the same date i. E13th september and flipkart initiated refund on 13th sept only but amount is not credited to my account, and according to flipkart it should reflect in my account by 23rd september but still money didn't came. After asking flipkart executive, they gave me reference no (Protected) told me to ask from bank and when i spoke to bank executive they are saying they can not help me with this no. They asked me for utr no, which flipkart executive is not giving. And when i again i ask flipkart they told me to raise dispute against bank in their grievance cell but when i gone to their cell they told they can't track with this number they again asked me for a proof that flipkart has initiated the amount so they asked me for utr number, and when i told them that i don't have utr number they told me to give me a confirmation mail provided on that date when amount was initiated, mode of payment and from which bank seller has transfered and his account number and ifcs code.
I request flipkart to give me utr no or this mail which states all the above things which i stated above so that i can show in bank as a proof and can raise grievance in bank.
Thanks
