SBI — Loss suffered due to Online Portal

Address:

SBI (Online Portal)

My wife and I are account holders in SBI Thrissur and currently in Chennai. We blocked an apartment in Chennai and had promised to pay our builder around 5 Lakhs as the first installment before availing the home loan. We added them as a beneficiary successfully but were unable to transfer the amount, although our transfer limit was set quite high.
We visited the nearby branch at Perungudi and they too looked into the same matter valiantly but to no avail.
We were compelled to take a DD from the branch just because the online portal was erratic and even the staff couldn't find the issue. This doesn't bode well for customers who are better off staying at home and trying to transfer funds. And moreover we were charged Rs.2000 as well for the DD.
Please understand that this is totally unfair.
We had to delay the payment and cut a sorry figure and pay an additional amount for no fault of ours
Please ensure that they compensate us for loss of time and money
