[Resolved]  CESC (Calcutta Electric Supply Corporation) — For 1.5 ac installation meters upgraded on 24-04-14 and on 26-04-14, but cables are not upgraded

Address:

Kolkata, West Bengal

Meters have been up-graded on 24-04-14 and on 26-04-14 as we have deposited required amount, but cesc men did not up-graded the cables with the mains attached with the meters. Man attended on 26-04-14 asked for additional money for cable changing and man attended on 24-04-14 neither changed the cable nor asked for money for that.
We are bit confused about this matter. Are the old cables fit for ac use? One man asked for money for cable changing and the other did not do that. We are not understanding the matters relating up-gradation of meters for 1.5 ton ac installation although we have already deposited hefty amount of money as cesc asked to do that.
Please let us know what has to be done?
