On 15th of February, 2021, I made a transaction with Amazon of Rs 1199 for ordering a Coolpad Cool Bass True Wireless Earbuds (TWS), True Digital Display Charging Case, Bluetooth Earphones with Mic for Calls and HD Stereo Music (Blue) But returned it immediately as i ordered the wrong one and opt for refund and Amazon has initiated the return and refund on dated 15 Feb 2021 but it has been over the 10-12 days I yet to receive the refund in my PNB account.
Customer service of Amazon is saying that we have refunded and generated RRN no., it's your bank problem and customer service of PNB is saying amount not credited and we cannot check through RRN no. Please do the needful and resolve my problem . This is a miserable condition I am facing.
