South Bihar Power Distribution Company [SBPDCL] — Delayed and no progress in New connection

I applied for a new commercial Connection on 8th of March 2021, it's been one month still I didn't get the connection, I'd registered a complaint also on 5th of April and they said my meter installation time is 9th of April but still meter is not installed and when I speak to consumer representative they ask me to wait for 2 weeks more and disconnected my call. This is so frustrating. Kindly help me out.
