Dear Sir/Madam,
I am writing with a connection of the second-hand computer set which was bought 6 months ago by me.
First of all, I want to express my dissatisfaction with a computer work. After a period of half year I realized that the computer broke down, probably the hard drive stopped working.
I expect you to repaire a device within a period of 14 days.
Lack of your positive response will force me to withdraw from the sell arrangement.
Yours faithfully
