Kerala State Electricity Board [KSEB] — Revising connected load

Address: North Paravur

Respected Sir/Madam,
We have build a new home recently by taking home loan & when we applied for single phase connection, because of one additional switch (that can be used for plugin AC in future), the sub Engineer asked to change the meter and advised 3 phase connection is required. Me and my child only living in the house, as my husband is abroad & the electric consumption also very less.
We got a message that says Rs-32117 to be paid in order to revise the connected load. We have checked with the KSEB office, & they says its because the 3phase service line is going through the main road & the line is yet to come to your panchayat road. So we have asked like there are so many houses are there & they are living near this panchayat road. The road is not for me alone. Its a panchayat road. In future if I pay this much amount, will I get the amount back if any other family require the connection? They said a no.. My question is KSEB should provide at least the service line without incurring fees from the consumers. For new connection we can pay, but what if they are going to provide the same line to others. That doesn't make sense. So I need a clarification on these. where can I contact? How can we get a new connection in this situation?
Already the bank has given the required amount. So we have no option to change the load now as the electric wiring and the connection also need to be changed for the 3phase connection & it requires money..
Your guidance highly appreciated.
Your's faithfully,
Sijimol
