Dear Sirs:
Our company, Fabulous Photo Agency, recently purchased several pieces of business office equipment from you. Our invoice is #3137, and we have paid the bill in full. After your movers set up our office, we noticed a few problems.
First of all, your movers bumped some of the file cabinets. Though this does not affect the units’ usefulness, they do look aged already. Another problem with the file cabinets is that you did not provide enough dividers to keep files separate.
One of the office desks is missing its keys. The invoice lists the desk as #19201. The last problem is that one of the desk lamps is not functioning properly. We changed the bulb, but it still doesn’t work right. That item is listed as #19249 on the invoice.
We have shown good faith in prepaying our bill. Please contact us at your earliest convenience to discuss how you will attend to the above- mentioned problems. We hope to do future business with you as our own grows. Thank you for your attention.
Yours sincerely,
Margaret Carnes
