You don't need to put your private banking information into your letter - instead, add your full name, address, and contact information to the top of the letter. A good bank will be able to look at your account based on your name and address. It's not wise to put your private banking account numbers and other information in an email or letter.
• Tone is important
The tone of your letter will be decisive factor which affects how the bank responds to your complaint. An irate, rude letter filled with insults or bad language will probably end up irritating bank administration, who will then be less inclined to deal with a complaint fairly and impartially. It's always better to keep a complaint letter factual, to-the-point, and very civil in tone.
Being polite and explaining the events that transpired, in chronological order, is often the best way to get your point across, without actually offending anyone. If a certain employee was involved in the fund transfer, name them, but don't cast aspersions on their character; instead, simply list what happened and then ask for action to be taken in the matter.
• The letter should be businesslike
If you're using a computer program, such as Word, to write your letter, be sure to use Word's built-in business letter template to structure and format your complaint letter. When you begin to write, Dear _____, Word's little paperclip icon will appear, and ask you if you're writing a business letter. If you click "yes" to this question, the software program will guide you through the process of creating a picture-perfect business letter that is very professional.
The best complaint letters are used to help a business refine their practices; they are informative, and useful to management, who are often quite open to feedback from customers. If you create a great complaint letter, you'll have an excellent chance of opening up a dialogue with the bank, and resolving your issues regarding the delayed fund transfer. Always keep a copy of the letter you sent in your files, as proof it was mailed, emailed, or delivered.
