Complaint Against Bank for Hidden Charges

Unexplained deductions from your bank account are not something you have to accept quietly. This letter demands the bank identify exactly which published fee authorised the charge and when you were notified, which is the question that gets hidden charges reversed.

When and how to use this letter

Banks deduct small fees hoping customers will not notice, so your first tool is your own statement. Download the last six months of statements and highlight every charge you do not recognise: maintenance fees, transaction fees, SMS alert charges, or penalties with vague descriptions. A pattern of unexplained deductions is far more persuasive than a single complaint, because it shows a practice rather than an error.

Next, download the bank's published schedule of charges from its website. Every legitimate fee must appear there with its amount and conditions. If your charge does not match any published entry, or the conditions were never met, the bank has no basis for it. Screenshot the schedule page, since banks occasionally update these documents after complaints arrive.

Send this letter to the bank's formal grievance cell, not the branch. Grievance cells operate under regulatory timelines, commonly thirty days, and every complaint gets a reference number. Ask two pointed questions: which clause of the published schedule authorises this charge, and when was I notified of it.

The move that usually ends the dispute: if the bank replies with a generic policy reference, write back asking for the specific notification sent to you about that charge. Banks that cannot produce it almost always reverse the fee at this point. If they still refuse, escalate to the banking ombudsman or financial regulator with your statements and correspondence.

Frequently asked questions

Can hidden bank charges really be reversed?
Yes, when the bank cannot show that the charge was disclosed and agreed to. Banks must publish their schedule of charges and notify customers of changes. An undisclosed or unexplained fee is reversible, and regulators take these complaints seriously.
Should I visit the branch or write instead?
The branch will usually deflect you to a helpline, which is a delaying tactic. Formal written complaints to the bank's grievance cell create a recorded case with a reference number and a regulatory deadline, which is why you should write instead of visiting.
The bank says the charges are as per policy. What now?
That response is not sufficient. Ask for the specific clause in the published schedule of charges that authorises the fee, and the date you were notified of it. Banks that cannot produce this generally reverse the charge.
