Dear Manager,
This is a belated email to thank you for your good service and hard working and courteous moving men.
We were very happy with our move on October 1, 2014 and would like to commend your two men for their hard work and courteous service. I told them that I would give them a good review so please let them know that I have done so.
We will certainly use your company for our next move later this year.
Sincerely,
Bill Franks
