I’m writing to complain about the quality of the computer which I purchase from your store on January 1, 2019. It unexpected went wrong a few days late. The monitor turned out to be a black screen. I read through accompanying instructions, and tried my best restart the computer several time, but it still failed to work. However, I’m sure there is something wrong for the computer. I am hoping if you can direct me to a store where I may return it for a new replacement within the next three days. Since your store has been gained a good reputation for customer satisfaction, I’m confidence that you will process my complaint at your earliest convenience.
