Complaint for Mobile Billing Error

When and how to use this letter

Start by downloading the itemised bill, not just the summary. The summary shows the total, but the itemised version shows exactly which calls, data sessions, or value-added services generated the disputed charges. Circle the wrong entries and compare them against your plan's tariff, which you can usually find in your welcome email or the operator's website. In a surprising number of cases, the error is a recurring subscription to a service the customer never knowingly activated.

Pay the undisputed portion of the bill on time. This is important because it protects your credit record and stops late fees from piling up while you fight. When you pay, note clearly that the payment covers only the undisputed amount, and keep the receipt.

Send this letter to the operator's nodal officer or appellate authority by email, not just to the call centre. Call centres can only offer scripted resolutions, while the nodal office handles formal billing disputes and their decisions are recorded. Give a fifteen-day deadline and state the exact credit you expect.

The tip most people miss: ask for the activation record of any disputed value-added service, including the date, time, and method of activation. Operators are required to keep this consent trail, and when they cannot produce it, the charges are typically reversed immediately. If the operator still refuses, escalate to the telecom regulator's complaint portal with your correspondence attached.
