Indian Oil Corporation [IOC] — non delivery of my refile

Dear Sir,
I am consumer in M/S Veerabrahma Indane, Chinna Chowk, Kadapa and my Consumer no. is 6016. I had booked to refill a cylinder on 21st Oct 2019 and got Ref. No. 460883. ETD : 3 - 5 Days. They generate Cash memo on 25th Oct 2019 with Cash memo no. [protected]. But still today i.e., 30th Oct my cylinder is not delivered. This morning I call to office to know about my delivery in office they says that Auto is on the way and they gives delivery boys number, I call him but he simply replays that he can't come to my home, if i need a cylinder i have to go to bring my cylinder. after that i call to office again and informed the same. this time in office they replayed that this evening they will deliver my cylinder but they don't. . still I got no cylinder.
So finally I Complaint to you that take a hard step against these types of system created by some distributors. Thanks
