Tamil Nadu Electricity Board [TNEB] — Change to my existing Tarif without notification

Address:

Ricotta Road, Hosur

I do have 2 connection at my location, one is the domestic connection for my home and the other is a commercial connection for my petty shop attached to my home, The bill which i used to get for the commercial connection was (Rs. 5K), which was way beyond my consumption for using just a fan, light and refrigerator in the shop, for which i had given a written complaint to the Foreman who accepted the letter without any acknowledgement and there was no action taken, hence i had not paid and the service was disconnected and i was constantly being harassed by the authorities, hence applied for a new connection as the earlier commercial connection was disconnected and account closed. The new application for the new connection was accepted and the meter sanctioned but i was not given the meter stating the payment has to be cleared for the old meter, and also they had disconnected my home connection, and now that i have paid the pending dues the meter has been issued to me but no one has come yet to fix the meter. Also as i'm constructing on the first floor for which was again harassed saying that i need to get a separate connection for the construction work with Tarrif 6, hence i had argued with the Foreman stating that Traffic 6 is only if the construction is only above 2000 Sq Ft, then he handed over the commercial meter which i had applied for but they have changed the Tarrif of my home connection to 6 without notice or what so ever,
I would also like to bring this to notice that though there is an online application process, the form once filled needs to be handed over at the desk in the office and they asked me to pay above and over the normal application charges, and was informed that it is mandatory to pay the amount to get the connection, i would like to know why it is mandatory to pay an amount over and above the connection request charges, would like to get vigilance involved to investigate and punish the concerned person so other consumers are not harassed in the similar way
