求英文道歉信

Dear customer,
I am the GM of the hotel.I am sorry to hear you are not pleased with us.First let me thank you for your coming to our hotel.You are a friendly and polite customer.Second,I would like to make an apology to you for our bad service. A few days ago you went to our hotel.When you got there,our waiters didn't help you with the baggage quickly,which you had complained about for many times.As soon as I knew about that,I felt very angry.How can we do that for customers?Now I am glad to tell you that something has been done .
The waiters who were on duty that day have been criticized.They have made a promise that would not happen from now on.So I hope you can forgive us and come to our hotel again.
As we know,customer is the God.If you have any questions or suggestions,please call us anytime anywhere.
Thank you again.
