Like "Hey Type1Lou, nice to see you. I have been through similar adventures trying to get needed information from a doctor's office, and playing go-between. Ping pong ball is right. It is even worse when you are trying to get a reimbursement you are owed. And I agree, some of these companies are so big that emloyees can't keep track of each other. Great idea to write those letters. They help make it clear what you are looking for and they may come in handy later. And people take letters seriously. "
