State Bank Of India [SBI] — pending home loan

I applied for a home loan one month back and i was told that home loan will be sanctioned within 14 days of submission of application but till date no update. I am writing this after knocking all doors. I applied in the main branch of sbi at faridabad but loan will be sanctioned from sector-16 branch, faridabad. When i went to sec-16, the people are saying that its main branch's issue and main branch people are saying that its sec-16's job. I am tired after roaming in each of your branches. Moreover, the cheque provided to you have also been misused because at the time of legal formalities, i was asked for a cash payment which i made to the lawyer after consulting the sbi representative but now cheque has also been encahsed. I cant understand why double payment is being charged from me, when the loan is not being approved. Main branch, faridabad could have told me initially in case of any discrepancy so that i would have selected some other bank. Its really disgusting that after moving from pillar to post, there is no update. I am really shocked that in today's time also sbi people are behaving like this. Its my humble request to kindly update me so that i can move to some other bank as i have already paid 10% to the seller which is at stake. Please help me which i am expecting from you end so that i can move to some other bank in case sbi denies to provide me the loan.
