Flipkart — Pickup of product is done but return is cancelled without reason and not refund not initiated

Address:

Vaishnavi Summit, Ground Floor, 7th Main, 80 Feet Road, 3rd Block, Koramangala Industrial Layout, Bangalore, Karnataka, India - 560034

I ordered a Malabar gold pendant, i see that the product finising is not good, so that I requested the return and my return is approved from Flipkart, the courier picked my product from me on 26th June 2022, but refund is not initiated and return is in cancelled state .
I call flipkart many times, almost 50+
They give me date of 3 July, then one cs told me wait 24 hours, again next 48 hours and 48 hours, but in help section my issue shows resolved, but no call, email i was received from Flipkart, i requested call back, but every time they just miss call, or disconnect if i receive the call, or they send massage that "we are trying to call you but did not connect".
I totally frustrated from their services, they just frauding and looting coustomers.
