To Whom It May Concern
I am writing to express my deepest gratitude to TransLink with regards to helping me retreive lost property on one of your vehicles on June 26, 2007. I would like to thank the driver, the customer informatin service and lost property staff especially for their outstanding quality of service and care for customers. I wish that TransLink will continue to excel in their superior service and look foward to my next TransLink trip.
Your loyal customer
