Complain About a Billing Error | Letter-Writing Guide


Keep in mind that most errors are unintentional, and that most businesses want to address and clear up their customers' complaints quickly. Avoid aggressive, accusing language. If two or three letters sent to lower level managers do not resolve the problem, send one to the president or CEO of the company. In each case, be firm but polite.


1. State all the relevant facts concerning the case in question.

  • On December 8, 2018, my wife and I made a reservation at your hotel for the night of December 20. We secured the reservation with our credit card, but were unable to keep the reservation. We called two days in advance to explain our situation to Mr. Doe. He said he would cancel the reservation without a penalty since we had called early; however, when we got our credit card statement, the charge from your hotel was still listed.
  • On Thursday, April 3, I ordered the following CDs from your company: Bach's Two and Three Part Inventions, Mozart's Requiem, and Glass's Glassworks. The following week I received only the Mozart disc, but was charged for the other two as well.
  • As you can see, I have returned, unopened, the JVC VCR that was sent to my home on December 13, 2018. I did not order the machine and do not want to be charged for it.
