Dear Sir:
I am writing to complain about the quality of the brief case produced by your company.
I bought a brief case which cost 1080 dollers in May20th.But I found it can't locked easily only few days latter.
I demand refundment or repair asap.I'm so discontented that I hope you could pay high attention to this letter and put an end to such things.
Thank you very much.I'm looking forward your reply.
yours sincerely,
