Good afternoon 

I have contacted your good self twice and supplied  evident of the insurance on the property above ( part of the master planned terraces at summerlin) for the period of May 2012 to May 2013 . To this date I have not been credited the over charges your good self imposed 365 USD. on a monthly basis X 12 month without consent and illegally without any approval . 

Twice over past 90 days , I have asked for the refund to take place and to my dismay I have been told today Thursday June  6,2013 at 11:02 AM. By the customer service provider that : 
- there is no claim or complaint notes on file 
- there is no refund been issued since The company GREEN TREE SERVICING DOES NOT HAVE insurance coverage on file for the period mentioned above 
- the customer service young lady supplied me with this email as last reresources lease be kind to advice
