Dear [Name]:

One thing we pride ourselves in is our immediate attention to settling claims for our customers and having checks sent out promptly.

There is very seldom the long interval between the filing date and the payment that we are unfortunately experiencing now. We are told [explain briefly why the delay exists].

This is as upsetting to us as it is to you, and I want to assure you that we are working as fast as we can. We will keep you posted.

It's always a pleasure to be of service to our valued clients. We appreciate your business and the confidence you have in the [Agency].

Sincerely,
