Indane Gas Agency — About New Gas Connection

Dear Sir/Madam, Recently i have (Brother) taken New Indane gas connection in Manchar village 410503. Kulswamini Distributor officer, Manchar has taken Rs.8700 for double cylinder connection. If we want only double cylinder, regulator & Shegadi then its really require Rs.8700 amount. We dont want anything extra apart from this item then what is actually price. And give me suggestion what should be i do for minimizing that amount.
