I came to know that my saving account has been debited for rs. 118.00 on 09/11/18 towards adhoc stmt chgs incl gst 210118-mir[protected] without any information. I don’t remember going to any branch for requesting any statement. When i reach to customer care they cant provide proper solution.
Kindly clarify why i have been debited with the above said amount.
