ICICI Bank — Icici bank charged 826 rs, never opted for demat account

After checking my bank statement, and found 826 had been deducted as dp chgs till apr-23 from my account on 26/05/2023.

I have never opted for or activated demat account services and never used my demat account. There was no prior notice. I was not informed at all by the icici bank regarding this. There was no sms to my registered mobile number for this deduction.

Please refund rs 826 back immediately with the charges which have been deducted in the past also and close this demat service.
