Call me naive, but I am inclined to believe the agent that wrote that he may, in fact, don't know what to do. Would I take it further or take no further action? Hmm, that is a good question, depending on how comfortable I am with my knowledge I could just send in a note saying thank you for your letter, there is no problem, but if one should arrise, I will be writing at such time. Else, if you are getting your refunds, why steer the pot?
