Rajdhani / Yamuna Power [Bses] — bill name change / application no. [protected]

Address: Mohan Garden, New Delhi, Delhi, 110058

I have already submitted all documents for name change on my electricity bill since 11 jan 2019

Application no. [protected]
Ca no.[protected]

But still not changed customer name on my bill

I've visited 2/3 time in a month for last 4 months but they give me a different excuse... Like - that's server down or head person is on leave... Or it will be done in next month... But still i'm not received my updated bill... Now i'm frustrated... I need my updated bill because my many works delay for that... So i request please help me... And update my bill name.
Thanks
