Sub.: Complaint regarding excess bill amount for the month of .............. (Postpaid mobile no. ..................)

Dear Sir/Madam,

I am a resident of (House Address). I have been using your company's mobile no. ............. for the last few years. The number was obtained in my own name. I am surprised to have received the current month bill for this mobile number with such an excessive billing amount.

Please note the following details about my mobile number for your reference and verification.

Mobile no.: ...............
Connection: Postpaid
Current active Plan details: ...................
Bill for the month of: .............
Bill number: ................
Bill amount: ...............

My monthly telephone bill amount generally ranges between (Amount) to (Amount). As you can see the bill amount as mentioned above is almost three times of my regular bill amount.

I have gone through the bill copy in detail and I noticed that I have been excessively charged for STD calls, which I have never even made in that month. Kindly verify this at your end. I am absolutely sure that I have not made any STD calls at all last month.

Therefore, I request you to kindly provide me a corrected bill for last month so that I can make the payment and continue to use the service. In case you do not correct this error, I shall be bound to lodge this case in an appropriate consumer or legal forum. I will also discontinue your company's phone connection.

I hope you will attend to my complaint urgently and resolve it at the earliest possible.

Enclosed herewith a photocopy of the concerned bill for your ready reference.

Thanking you,
Yours faithfully,

(Name of the Complainant)
