Address:

Virudhunagar, Tamil Nadu, 626126

My consumer no: 5225, jk indane gas agency. Booked three times in january itself. Still cylinder not delivered.in nearby house the delivery person had said as we do not give extra rs. 50 so that i made it as door closed and not delivering. Was it rule to provide extra amount than specified in the bill? Even though we provide rs.10 to rs 20 extra than bill, still the delivery man has done this and he frankly speaking this to nearby house and going.
