I ordered a chair from amazon.in on 7th Sept, 2021. I returned it on 8th because did not expect it to be so uncomfortable and tiny.
The refund from amazon was initiated on 8th and was supposed to reach my account by 13th Sept, 2021.

It hasn't anymore. From past 2 days canara bank and amazon customer service guys are asking me to call each other. And there's no solution. I am fed up.
The reference number given by amazon does not give any information to the canara bank customer care guy. what to do? reference number: #SJDXMW5T0000KSGLT7HJ

Just send the refund. Pls resolve this
