Rajdhani / Yamuna Power [Bses] — Wire Replacement Which is nearly 60years Old

Address: A1 Hauz Khas Aurobindo Marg New Delhi 110016

Dear Sir,
My house was constructed in 1960. At that time 4mm wire was installed from the pole till the main meter. Now that wire has so many cuts and joints that it keeps sparking every now and then and the house electricity power keeps cutting off. I have to raise a complaint and BSES Rajdhani technician comes and joins that same old wire.
I request you to kindly change that old wire and install a new heavy wire as soon as possible. I have given written requests in your office but nothing has happened. I have all required documents but no replacement has happened. The technicians say you submitt some fees in cash and it will be done. I dont think any such fees is required to paid in cash.
