Car cleaning complaint mail from customer

Here's an example of a car cleaning complaint email from a customer:

Subject: Unsatisfactory Car Cleaning Experience

Dear [Car Wash/Detailing Company],

I am writing to express my disappointment and frustration with the car cleaning service I received at your establishment on [Date of Service]. I had taken my [Make and Model of Car] to your car wash and detailing center, expecting a thorough and professional cleaning. Unfortunately, the experience fell short of my expectations.

The issues I encountered were:

I had expected a higher level of service from your company, especially given the prices you charge. I would appreciate it if you could look into this matter and take steps to ensure that your customers receive the level of service they expect.

I would like to request a complimentary re-cleaning of my car to rectify the issues I experienced. I would also appreciate it if you could provide a discount on my next service or a refund for the portion of the service that was not completed as promised.

I hope that you will take my complaint seriously and take prompt action to address the issues I have raised. I look forward to hearing back from you soon.

Sincerely,

[Your Name]
