Dear Mr./Mrs. XYZ,
Your kind correspondence, (dated….) indicated that we would be receiving a refund for the unused portion of prorated insurance provided under the above mentioned referenced policy.
Around this date, we have not yet received this check. Since we have relocated, we are naturally anxious that the check was sent to the incorrect address.
Could you please let us know if the check has been mailed. If not, we would appreciate your authorizing that you be sent to your address indicated above.
Thank you for your attention to the matter, we are waiting for your replay.
