Tamil Nadu Electricity Board [TNEB] — Power cut in ambattur market

We are facing power cut issues atleast weekly once that too in the night time for many hours. We are not getting proper response from the ambattur especially numbers given to contact them are totally waste.. Even if they attend the call also they will not give proper answer. Why often power cut issue happens ambattur market, ambattur ot.. We are paying the eb bill without fail. Are we consuming electricity for free.. Really very frustrating.. We have sit in the midnight without power cut for many hours like in old age.. Either fix the old wires or atleast ask eb persons to attend the call and answer politely.
