Indian Oil Corpn. / Indane — unauthorised charges for replacement of regulator

Address: Agra, Uttar Pradesh

Dear Sirs,
I have an Indane connection no. <MJ 8808> in my name from Ms. Marut Gas Service, New Agra, Agra.
My regulator became defective today
i.e. 23-2-11.
Ms. Marut Gas have charged Rs. 150/- for replacing the regulator today. They have kept my old regulator and have refused to issue a receipt for Rs. 150/- or for the regulator.
This action of theirs indicates that they should not have charged me for the regulator and should have replaced it FOC.
I shall be grateful if you will help me and get my money refunded from them.
Thanx and regards
P.P. Dhir
