Subject: Complaint about Mistake in the billing period.
I’ve just received your invoice No xxxx (dated) for the half yearly concerning my telephone No. XXXXXXX, is inappropriate.
In this bill there are errors, which I wish to bring to your knowledge for rectification. First coming to the period of the bill, it is calculated for six months from [dd/mm/yr] to [dd/mm/yr] but I have already paid three months of it from [dd/mm/yr] ] to [dd/mm/yr] and only have to pay from [dd/mm/yr] to [dd/mm/yr].
Firstly I want to bring to your notice that All eighty phone calls are showed in the statement, out of which twenty-eight are of the previous three months and remaining comes to the current three months period. Secondly, I have been charged for two incorrect ISD calls.
I am sure that, there is some error with your accounting or there is usually some mix up someplace. I request you to kindly look into the matter and get the telephone bill corrected. Normally, I shall be obliged when you can produce the details regarding the all the local calls along with the ISD calls made.
Now I am sending back the telephone bill for the ready reference and essential correction. The payment for this current three months will be made the moment a rectified bill is provided for me.
