Dear Sir or Madam
Robot Goldfish
Last month, I bought a robot named Goldfish from your shop. I expected it to help me with the housework.
However, I am not at all satisfied with it.
Firstly, the robot never works correctly. You promised that the batteries would last at least two months, but i have to change them every two days.Also, the robot is so lazy that it is only willing to work for three hours every day. It is causing me a lot of trouble. So I plan to send it back to you, I would like to get my money back.
I look forward to hearing from you soon.
Yours sincerely
Susan
