Rajdhani / Yamuna Power [Bses] — Address correction

My billing address is different from the address of the registration of the property by a single character.
My billing address is 415/5 whereas my registry document has address 415-1/5.

When approached the BSES CHD they are saying it cannot be corrected and I need to apply for a new connection instead, which seems a little odd.

Hence request you to kindly look into this matter and assist.

Thanks.
