Dear,
Sir/madam

I brought a music system from amazon ie. Koryo kht4212fb before five months it works good sound good all are going fine till a day before. At present it had a small problem. When i a try to power on the system it doesn't work. I tried to connect it in another plug point and also used extension box it shows the same complaint. So kindly do the necessary action for to do service my music system under the company s warranty scheme. I tried to call your toll free number but no one was pick up the phone call. So pls do the needful.
