5th August 2010,
Mr. John Stephen
AMC Company Inc,
The purpose of writing this letter is to convey my sincere appreciation to you. The previous day, when I was unable to handle the client due to severe head ache, you have taken over the work from me, negotiated with the client and solved the issue. Thank you very much. I was in fact surprised by your caliber. Keep it up.
The extra effort put by you was very impressive and I have never seen such a committed person like you till date. It has been my experience that when employees accomplish quality customer service, they tend to be quickly promoted to the next levels of the organization. Based on the service I have received from you, I will not hesitate to recommend you for good position in our organization. Wishing you all the very best in your career.
