Nationstar Mortgage Mortgage Complaint

Nationstar Mortgage Mortgage department,

Conventional fixed mortgage Credit decision / Underwriting Utah

All I am trying to do is get the completed modification paperwork that I requested over 3 weeks ago. I am trying to do a refinance and the underwriter is asking for the completed documentation of the modification we had 4 years ago. I have called and emailed them repeatedly and every time they tell me they will mail it to me or email the document to me and I still have n't received the paperwork. I am going to have to pay for an extension on my locked rate because this is all we are waiting for!!!!!!
