To: ABC computer companyAttention: manager, sales departmentRe: request for refund of computerDear Sir,I bought a M brand computer from your store on 30th Sep 2009 at 6pm. It is a laptop computer, model 15TL50, with dual core processor, 2GB memory, 500 GB harddisk, and it is loaded with Window 7. Since the computer has been bought, I hardly use it. However, when I use it for more than 1 hour, it always turns off by itself without giving any indication. I have called your company hotline for help but they cannot offer me any solution. I am a student and I need the computer to work on a school project very soon. The condition of the computer is totally unacceptable to me. I am writing this letter to you, to request for a refund of the computer. This will enable me to get another one to work on the school project. Please grant me my request, otherwise I will approach the Consumer Association for assistance.Pleae find attahced a copy of the sale receipt, and records of fault report for reference. Please kindly reply as soon as possible.Thank you.Yours sincerely,xxx
