Dear [insert name],

I am writing this letter to formally register a complaint regarding the sub-standard parts of the computers I received from your company. I am a regular customer of your company and am appalled with the experience I recently had. The list of issues of the product are attached to this letter.

I called your customer service hotline and registered my complaint. I hope the issues I am facing will be addressed as soon as possible.

Regards,
