Akbar Travels — Refund not received from 4 months

I had a book of 29th March 2020, which got cancelled due to lockdown. Indigo airliens intimated me that they have transferred the refund back to the travel agency. The travel agency is not giving back the refund and it has been 4 months. They don't even reply and cut your calls abruptly without replying properly.
REFERENCE number- AT[protected]. My refund. Is to be returned fully as i didn't cancel the ticket. This is the worst travel agency ever and have the Worst service ever. Would never eben download their app. Please help me get my refund of approx Rs. 13000 back.
