Someone has fraudulently debited my sbi a/c no . 1095****063 by way of online purchase made thru atm card ending with 8177 between 14/05/18 to 22/ 05/18. Sir, I have lost my hard earned money for an amount of Rs. 87503/-.
Please look into the matter and be kind enough and credit my account with the same amount.
