When writing a complaint letter for a bad product, some things must be included for it to be effective. Before you take a look at a complaint letter example for bad product, you should consider the following key points:

01You should show urgency and disappointment, but you should be respectful.
When writing a letter of complaint about a bad product, your letter must use strong, yet respectful language to convey your level of disappointment.

02You need to review the refund or exchange policy.
All reputable companies ‘provide goods’ or services’ policies, and they are made to address these types of situations.
It is up to you, as the consumer, to learn about the company before you write a letter. It makes no sense to demand a refund when there isn’t a refund policy in place.

03You will need proof of purchase:
While the company likely has proof of your purchase, it is still up to you, as a consumer, to bring forth some sort of receipt or invoice.
This is needed to strengthen your argument, especially since some unscrupulous businesses may try to deny records of you ever having purchased a product or service from them. You may have more difficult if you made a cash purchase.
You may also attach photographs to show that there are no signs of physical damage to the product.

If a product is delivered to your home and is defective, it is not your fault. You should reach out to the company using this complaint letter example for bad product:

On [date], I ordered a [insert name of product] from your online store for which I paid [insert exact price].

I browsed the user manual several times, and to no avail, there was no solution. Afterwards, I contacted tech support and still no solution.
I was given the case number [insert case number], and after three weeks, no representative of your company has reached out to me.
Though it is heart-breaking, especially to part with a product that I wanted for so long, I must request a full refund. The customer service I was shown has been subpar at best.
Attached, you will find photographs of the product as proof that there was no tempering. You will also find the receipt outlining the charges made to my account.
I would like to ask that you respond as soon as possible to my request. Please provide instructions on how to go about returning the product and receiving a refund in full.

A complaint email example for a defective product that isn’t working at all

If the product arrives defective and does not work at all, then you must say something about it to the seller or manufacturer. This is one complaint letter example for bad product you can use in this situation:

03To whom it may concern,
My name is [insert name], and I am a frequent customer of your business. Unfortunately, I am also a disgruntled customer at the moment.
After years of purchasing products from your company, I have grown to trust and rely heavily on your products for my business purposes.
On [insert date], I bought a [insert name of product] from your [insert location] store in [insert city/state/town].
I was assured by the sales representative that this product was one of the most reliable products in the store, and if there were any issues, it would be covered by the warranty.
Though this is commonplace for sales representatives to say, it is quite odd that the product would not work at all once I tried putting it to use.
After emailing the store, I was told by the sales representative that I should have tested the product before purchasing it.
As you can imagine, it is quite unreasonable to expect such a large item to be tested in such a small space and in an inappropriate setting. I have written today to demand swift action against this representative and for an exchange of this defective product.
Attached, you will find the transcript of the email correspondence with the sales representative in question. You will also find proof of purchase for this product.
I await your timely response. Thanks,

A complaint email example for poor-quality food products

We go to restaurants to take the burden off when it comes to cooking. We also like to enjoy good quality food. When the quality of the food is not as expected, you can use this complaint letter example to express your disappointment with the food product:

05To whom it may concern,
I visited the [insert name of restaurant] on [insert date of visit] for a family celebration. Amid all of the excitement, our group was disappointed by the poor quality of the food delivered to us at the table.
Our first issue was with the speed of the wait staff. Despite the restaurant not being full, we waited nearly an hour for our appetizers to arrive.
When we received our chicken platter, we discovered that it was cold. Even worse, the chicken was raw on the inside. When we raised the issue with the waitress, she left to speak with the manager. Then, she simply brought us the bill without addressing the issues.
We paid the bill to avoid any commotion, but the entire experience left a bad taste in our mouths. It wasn’t from the chicken despite its rawness.
Since this restaurant has been a part of the community for a very long time, it would be unfortunate if reports of this nature were made to the public.
For that reason, my family and I have decided to give this establishment a second chance to right their wrongs.
If you are interested in proving to us that this was the right decision, do not hesitate to respond to this email. You can call my cellular phone: [insert phone number].
