Ajio app - Refund not issuing

I had returned a product that I bought from Ajio on **th March ****. It was a white kurta set from Juniper brand. I had returned exactly the same product that I had received. The last date for issuing the refund was *st April. They denied refund and instead blamed it upon me that I have sent them a non ajio product instead of the original product that I had received. This is completely a false allegation and harrasment on an innocent customer like me. I want my refund to be issued to me and strict action to be taken against ajio warehouse team for their lack of work effectively. This incident taken upon my pride. My return Id is RT********.
