Bank Of Maharashtra — FD Interest Rate changed without reflecting on the website

Address:

Nagpur, Maharashtra

I created two FD in Bank of Maharashtra, on 9th and 10th July 2015 respectively. I created the FD with tenure of 1 year, and as per their website on this two days, the interest rate that was showing was 8.5%. However, when I created the FD, it was created with 8.25% interest only. Then I emailed the BOM officials, and they simply emailed me saying that the interest rates have been revised from 9th July. Then on 11th July I got the email that the revised interest rates are reflected on the website. But now my question is, I have already locked my money with lower interest rates just because as these guys didnt updated their website prior to applying the revised Interest Rates. They should provide the customers the same interest rates on the FD's created on 9th and 10th July 2015, as it is their (BOM) mistake that they didnt update their website first.
