Dear Sir or Madam,
I’m writing to lodge the complaint about the poor quality of an air conditioner that I purchased from Sun Appliance Company.
Frankly speaking, Sun Appliance has always been my favorite. On April 4, 2007, I bought the air conditioner (serial number 12345) from one of your chain store located in Lang Fang. The machine operated well at first, but ten days later, there was a fault that bothered me, that is, the fan made so much noise that I could not sleep well at night. Worse still, the cooling system didn’t work well and the machine began to leak recently. Its poor quality ruined almost all my previous impression toward your products.
I strongly suggest that a repairman or a service engineer should be sent to my home without delay. I wonder if you could pinpoint the exact cause of the malfunction as soon as possible. If you can’t, I am afraid that I will request for full amount of refund or a new air conditioner.
I would appreciate all your assistance in this matter. If you have any questions, please don’t hesitate to contact me. Look forward to your reply.
Yours Sincerely,
Li Ming
