State Bank Of India [SBI] — Duplication of internet payment

Address:	600017
Website:	sbionline.in

I have been debited twice for an internet payment of Rs 1011.24 towards the IIT CEED exam . While the actual payment was made on 22/04/15 the duplicate payment debit entry was on 09/04/15 even before the registration for the same had opened.
My repeated requests and complaints to my home branch to reverse this duplicate entry has not been done.
