Dear Mr. Alan,
I have your letter enquiring about the reputation and reliability of Mr. Robert of Excel Trading Co.
I have dealt with Mr. Robert for many years and he has never done anything that would make me doubt his trustworthiness. As you know, he worked for me for five years before setting out to start his own company. I never has any trouble with him during the years he was with me. In fact, with him around, I has peace of mind knowing my company was in good hands. Then he left to do his own thing. It was sad to lose his excellent service but I cannot stop him from doing what he wanted.
In short, I can say that Mr. Robert is reliable and you should have no problem dealing with him.
