Dear Sir or Madam,I am writing to make a complaint against your bad delivery service.I’m afraid that the enclosed CD player doesn’t work. It is the third one I’ve got to return this month.Other than the three I’ve had to return recently, I’ve always found your products to be excellent. I would be grateful if you could send a replacement and refund my postage.I look forward to your reply and proper resolution of my problem, and will until the end of this week before seeking help from a consumer protection agency or the Better Business Bureau. Please contact me by the address on the envelope or by phone at 6668888.Sincerely,Wang Hua
