On 4th july i made a payment of Rs/- 100223.6 via internet banking for LIG flats. While doing txn. I got msg on screen that my txn. has been declined later i got a deduction (100223.6) msg from SBI with a ref. no. But i didn't get any confirmation msg from DDA yet though amount has been transferred to DDA as per bank statement.

That is the site on which i logged in. Even now i am not abled to login as its showing incorrect details. I am tensed as i didn't get my money back and online payment status is showing successful on SBI but i don't have any acknowledgement slip from dda.
