BSES Rajdhani — Incorrect Bill Amount

I would like to report that today I received the BSES bill of Rs 6940 which is due by 10/7/2021 and the bill is for last 91 days. However I have paid Rs 430 on April 2021, Rs 2650 on May 2021 and Rs 2810 on June 2021. This is really strange. And when you call the BSES Helpline to get a clarity on the same, they have no proper answer to your query. This seems like I am paying for the same period twice which is really not acceptable. I need the correct bill and I would be more than glad to pay the same.

Thanks & Regards,
Suswagata Dey
