Nationstar Mortgage has failed to respond to our requests and clarification of the following : 1. They are not crediting or applying the correct payment amount we made towards the principal since XXXX 2016. 
2. They created an escrow account to pay the property taxes and the home insurance without our knowledge and/or consent. 
3. They made payments for the property tax for a bill we had already paid on time, they also paid the home insurance that was not due until the end of XXXX, 2016 4. The Tax Collector office rejected the duplicate payment from Nationstar and sent the money back to them ; however, Nationstar still has an escrow balance on our account even though the Tax Collector returned the money to them We have several requests in writing as well as by phone to correct the principal balance, which is off by about {$5400.00} to no avail. We get transferred from one person to another and they promise to send an explanation letter but they never do. 
We requested to close the escrow account since we are taking care of the property tax and home insurance ; they still have the account and the balance due for something we do not owe. PLEASE HELP. 
Nationstar has refused to modified our loan twice, the current rate on our loan is 5 % which is about 1.5 % above the current rate
