Dear Sir / Madam，

I am Li Hua， a frequent customer in your restaurant． I have been pleased with your excellent service for years， but now I'm writing to express my dissatisfaction with the poor service of your waiters．
Yesterday， I went to your restaurant to have lunch but I had an awful experience． When having beef noodles， I suddenly found there were two flies in them， which disgusted me a lot． So I asked the waiter to change another dish． Against my expectations， he didn't change it but said in a rude manner that he was too busy to solve the problem． Needless to say， the way of treating customers was really bad． It's my sincere hope that you can investigate the matter seriously and make a formal apology to me．
I look forward to your better service next time．
