ShoppersStop — Refund not received

I had placed an order Order no:[protected], on 7th of July 2022, amounting to 1821.82 INR . On 10th of July I received a totally different, stained shirt and immediately placed an exchange request. Next day that stained shirt was picked up by their courier partner, but after that there is no reply from their side, these people are literally making me fool since 3 months and neither they are sending me the shirt nor refunding my money.
I have called them so many times, every time they create a case ID and promise me to give resolution within 2-3 days but they never send any reply and resolution . I am fed up now and their such actions are forcing me to lodge a police complaint.
