State Bank Of India [SBI] — complaint regarding the deduction of 898 rs during card payment

I have complained twice for the deduction of 898 rupees during card payment at dmart, krishak nagar branch, Raipur on the date of 13th October and when I updated my passbook today I got information of not getting my money even after waiting for 45 days as per the time asked by customer care to return that back regardless of all complains, so please try to cooperate with my problem and help me by returning my money back to my account which is very much required for my education purpose since I belong to poor background hence this amount means alot for me
