Redbus — Incorrect boarding location

My name is Parikha and ticket number is : tsb[protected], pnr: 693777.

According to my ticket the bus was to depart from Kamta chauraha, shaheed path, lucknow at 9PM, however, after a lot of confusion the driver told us to reach dehria chauraha near charbagh which was 30 minutes away from the boarding point and hence I missed the bus. I wanted to request a refund for the same. Kindly help.
