Bharat Gas (Prateek Enterprises) — Cylinder not delivered but delivery message received

Address: Bangalore, Karnataka

My consumer number is 53605174. I have booked a cylinder and received a message of delivery on Sunday (22.3.2015) but no cylinder was delivered to me. I have been calling the customer care for over a week but most of my calls are missed. Some are received and my complaint is heard and they give me some numbers of delivery boys which are all switched off (till now i have got two numbers)
