Dear __________

Greetings from the Philippines!

I am ____________________, in charge of Medical Refund in ___, I would like to inquire regarding our insurance.

Per record we already sent the documents for AAA insurance refund, Did you receive it?

May I know if there's any additional requirements needed for us to be able to make a refund.

Is there any refund made from insurance?

thanks,
luchie...
