Nationstar Mortgage LLC Denied me informaton on the account, increased payments on account without notifying me Lewisville Texas

In 2013 I requested a refinaing of my home loan through a law firm, Michael A. Rabel & Associates, LLC at a cost of $4,200.00. They did a remodification and sent it to nationstar mortgage, llc and since that time it has been constant confusion. To contact nationstart via customer service takes an act of congress. I get transfered from one deptment to another and nothing ever get done correctly. This whole process was to prevent losing my home since I was retiring and i would not be able to keep up any large payments. Since then my payments have been increased without my being notified and to top it all off no one at that company will talk to me or tell me why my payments or being increased. i make monthly payments via their website and suddenly they disapear and nationstar can't find them and then i have to go through my bank gathering information because of their incompitance. To date (1-26-2015) i have been on the phone for over two hours trying to get my payments straight and to get my account inorder and to no avail. one department does not talk to another department and therefore nothing gets done. I am retired with limited income and cannot afford a large monthly payment yet these people don't seem to care nor do they to care about customer service. I get angry everytime i have to try and contact them. Signede, Thomas Smith
