State Bank Of India [SBI] — gas subsidy

Address:

Hyderabad, Andhra Pradesh, 500081

I have changed the bank account for gas subsidy from icici bank to sbi. Since i have closed icici account. I went to sbi, indane gas agencies to confirm that i have changed the account for gas subsidy credit. But from last 3 re-fills when i had changed the account, i am not getting subsidy, if i go and check the indane gas site, it is still showing icici bank is linked, if i go indane gas agency they say i must go to sbi bank to modify the details, if i go to sbi they say i have to change it at indane gas agency. I am roaming and struggling from last 5 months. I want to give compliant on both the firms. This proves the government company. Please suggest
