Sabha Indane Gas Agencies — Delay in delivery

I booked the cylinder through online 4 days before and I finished the payment also.My consumer no is 7043722.Bui still now we didn't get the cylinder..I belong to Sabha Indane gas agencies.51, cart track road, Maduvinkarai, Guindy, Chennai.. Very worst gas agency... They are not at all responding properly.. Very poor customer service.we belong to butt road, Guindy.They are not delivering the cylinder more than 10 days in our area...If I asked means they are telling that the delivery person Siva not feeling well..so only delay like that...I don't know whether the whole gas agency is depending on that one delivery person.very worst customer service..I request you to please look into the issue..
