State Bank Of India [SBI] — I'm complaining about Cash deposit machine transaction initiated by my staff with SBI Saravana Bhawan Branch

Address: Chennai, Tamil Nadu, 600040

My staff, in chennai tried depositing 21500/- into his family members account in Rajasthan on a June 2/2017. As per records they say that the money was not excess and has been taken back by the staff itself but they do not have evident proof of the same. They aren't willing to look at camera recording as well for the same. It's been a month and there's no update from the banks side. I would like you to take strict action against the issue and let us know who is guilty for taking the cash. Please help us or guide us to consumer court for the same and we shall see what is to be done.
