To Whom It May Concern,
It is with extreme dissatisfaction that I am writing you this letter. I have ordered a few computers for our company from your's and, sad to say, I am not content with what has been given to me.
This is the first time I have come across such trouble from your company so I would like to believe this is a one-time event and is not a representation of your company’s quality. Because of this, I hope you will address this matter seriously.
I am hoping for an intervention from your office and that you sort out this issue immediately. Thank you for your kind consideration and I look forward to hearing from you soon.
