My consumer no is;cx14408391, sumangaladevi. K. Allugadabhavi, mettuguda. Telengana -500017. I booked my cyliinder on 2-3-2018, till this time they are not ready to supply my second cylinder. I deposited my money and why iam suffering...? They are irresponsible people, doing black sale also..., because online bkng machine told, march 17th cylinder done., but they fail to the proper benificiery (Me).
So pls take proper action towards the culprits.
