I'm one of your customer having LPG connection, consumer no:1931 dated 17/11/2007 at your distributor, m/s BHASKAR GAS AGENCY, 1/260-B, NEAR GARUDAN KULAM, BARRACKS, WEST HILL, CALICUT, KERALA. PIN:673006.(distributor code:621705) .
I received my second cylinder connection on 26/2/2009 by paying Rs.2150/-.along with a COMPLIMENT worth Rs 380/- which have been charged from me. When I enquired about the detailed bill, they gave only the subscription voucher for Rs 1250/- and a bill worth Rs 326.50/-. I rejected the compliment but they said that it was a company offer and they even charged money for it.Kindly clarify the genuiness of the compliment and the chages for the second cylinder.
