Punbus / Punjab Roadways — Refund not received even after 4 months

Hello Sir,

I had bus booking for Punbus with pnr-no:[protected] and ticket-no:[protected] from Delhi bus stand to Jalandhar with amount of 1060.
Later, I had to cancel this booking and I did this as per provided guide line and it was done successfully.
But I never get my refund after cancellation.
I write multiple emails to Punbus team but even after 4 months, they have not refund my money.

I am attaching the e-ticket also.

Thanks,
Varinder Pal Singh
