State Bank Of India [SBI] — charged 8850 for non-submission of rc book

Address:

Bangalore, Karnataka

I have been charged 8850 by SBI in the name of non-submission of RC book.I have never received any notification regarding RC book submission.When i complained to customer care they closed the ticket stating the charges are according to the services charges mentioned in the site. But in SBI website there is no such information anywhere. I also visited the branch, they simply took the complaint letter and did nothing about it. I have really no idea what to do about this situation. 8850 is a big amount for me
