NM mail refund checks

  1. Does anyone know information on NM refund checks. I returned a bag well over 10 days ago and was supposed to get a mail check because the refund amount was greater then $500.00. I still not have recieved it yet. I just did online chat with the most idiotic customer rep ever and he kept telling me to call the store, when the store tells me Dallas HQ handles the mail check refunds. Anyone ever gone through this before?
