Tamil Nadu Electricity Board [TNEB] — regarding tneb bill non-payment - chennai

Hi,
I'm writing this to know about non-payment of tneb bill.
I have bought an plot last year having single phase supply for sump motor. Since we haven't use and residing in bangalore, we didnt check the bill. Last week when i just went and checked the status of the eb connection, i came to know that there was a bill of around rs.7000 is not paid from june'2017 (Almost 18months) and the status is in disconnected mode. The corresponding location tneb office payment section officer told he cannot enable the connection as the system is not allowing to accept the payment and asked to goto aao office.

My questions are:
1. Since it is not paid for almost one and half year, is there a chance of permanent disconnection?
2. Whether aao office (R) can resolve our issue and enable my tneb connection again after i pay the dues?
