Indane Gas — Name Transfer for existing connection

Address: Kerala

Respected Sir,
My sister Mrs Elizabeth Thomas had a Indane gas connection from Sandhya flames Aranmula at Pathanamthitta ( consumer number-7187 dt Dec 1996), after marriage her name was canceled from the ration card so the connection has to be changed to my name. The Sandhya fuels asked me to pay Rs 800 to transfer it to my name and i deposited Rs. 800.But i was asked to pay an extra amount of Rs. 1900 as deposit by the agency . I have already deposited an amount at the time of new connection in the year of 1996 .
So please give an explanation for my problem .
