To the manager,

I am writing this letter to express how impressed I am with the service Renee has been giving me over the past few weeks.  Renee contacted me around 3 weeks ago after my initial enquiry and suggested I come in for a chat. Having been burnt by one of your rival agencies recently, I was very skeptical, but agreed to come in. Renee explained the services your company provides and re-assured me that my money would not be sent down the drain.  She made me feel at ease with my decision to join your agency and has proven her abilities quite well to date.

She has matched me with some very compatible women and seem genuinely interested in my quest for a mate. She has shown me the kind of service I expected and I am very grateful for her efforts. It is my opinion that she is a great asset to your company and deserves a pat on the back.

Thankfully yours
