Dear sir or madam ,
I am writing to complain about my most unhappy experience have supplied receptionists and doormen for your headerquarters.Recently the standard of the service they give has declined sharply .I am not forget the good relationship I have had forever in the past .And good relationship is so important to a company to development .For one thing ,when I made a call to inqure about something ,however the person who answered the call was very rude .And she interrupted me continually .So I had to go myself for your company ,but I was in your company ,your receptionist was kept me waiting a such long time .for another your doormen even gave that the misdirection .Needle to say, such a way of communicating with customers is unacceptable.I would like to suggest that the receptionist and doorman in question should be disciplined, and instructed on the proper way to deal with clients.This problem has affected our normal relationship .Would you please let me know whether or not your company can change this as soon as poible？I hope that the problem will get your kind consideration.And you look into this matter immediately and deal with it quickly and properly.Looking forward to your reply.
Yours sincerely
MaJing
