Subject: Grievance resolution letter
I am writing this letter to inform you that with reference to your letter no 89 dated 5th June 2012 sent to my office your grievance has been fully resolved. As you have complained that the bill of your mobile numer-9547863214 in the month of May 2012 sent from our company was of $ 1,058.05 but actually you have not many so many calls. In order to find the out mistake I manually searched all the outgoing calls made from your number. After calculating all the call costs the actual revised bill came to $ 459.02.
The inconvenience caused is deeply regretted due to the wrong billing done from our company. The mistake occurred as your actual bill was mistakenly swapped with another customer. I am enclosing a copy of your revised bill which you are requested to pay before 29th June 2012.After the deadline you will be charged a late fine of $0.5 dollar per day.
Hope that your grievance is fully resolved and it will be our pleasure to help you in case of any further queries.
