Abhibus Services India — Refund not received for payment failure

I tried making a bus booking from Bangalore to chennai and chennai to Bangalore on Apr 6, 2022. The payment failed somehow that day. My order ID is RB55871176B55871175A . I was assured of the refund between 2-3 days, it's been 8 days and counting and I have not received my refund. I've been trying to call, there is no agent availabel to talk. I've tried using chat option in the app and no agent is available to talk. Feels like I have been scammed.
