Indian Oil Corporation [IOC] — Regarding selling cylinders in black

Address:

Jalandhar, Punjab

Actually, I have booked cylinder 2 weeeks ago, and I received a message that your cylinder will be delivered shortly...but suddenly, after 2 days there was message that your cykinder has been successfully delivered, but I had not received it yet.So, I strongly put my dissatisfaction of this act.
This was not happened first time, earlier I complained it to the service station...but again I suffered from this kind of act which is shameful in itself.
