Indane — Unable to book Cylinder through IVRS/SMS/Internet

I am an Indane custome at Bangalore, Customer No.69022. Since about 15 days back I have been trying to book a cylinder through IVRS/SMS/Internet. But every time I try I get a message stating that I have booked a cylinder on[protected] and the same was deliverd on 03-02-15 and it says the cash memo number also. Thats all. I contacted various numbers. The computer at helpline[protected] is always slow. They told me to contact the dealer. I tried the dealer (Anusha Indane Gas Co., Bangalore) over the phone. They have four phones. But they never pick up the phones. Then I placed a feed back compliant in the Indane website. I got a reply to 'furnish bank details' . I again complained that I have furnished the same and had got the subsidy also. Again I got a reply to 'furnish bank details' . I tried the PRO number[protected]. Nobody would lift the phone. Then I tried Indane Head Office phone number[protected]. The person at the other end told me to call[protected]. I called this number. Somebody at the other end told me to call[protected] or[protected]. I tried these numbers. But nobody lifts the phones. Then on 14-03-15, I went to the dealer. A girl at there told me that the previous delivery details have not been entered into the system that is why I am unable to book it. She took my customer number and said she will book it from their end. But today when I tried the IVRS system, it says the old message itself, indicating that booking has not been done. What should I do ? Every time I have to go to the dealer, I have to take half day leave. Just for a two minute talk I have to apply half day leave. I sent an Email also to the dealer. But no response. Why don't the dealer pick up the phone ? Why nobody at Indane (Unity Building) picks up the phone ? Why doesn't the PRO pick up the phone ? Why the helpline doesn't help at all ? What should I do to get my cylinder ?
