Nationstar Mortgage company paid another client 's mortgage insurance out of our escrow account in XX/XX/XXXX in the amount of {$5300.00}. We had not realized the error until XX/XX/XXXX when we were notified from XXXX that our insurance had not been paid. Our insurance payment is {$3800.00}. I contacted Nationstar and was informed that an error was made. Our insurance was then paid by them but the {$5300.00} was never replaced in our escrow as we are told it ca n't be until they receive money from the client that they paid the insurance. They are unable to contact the client and therefore say our money ca n't be replaced. I keep being assured after numerous phone calls it will be taken care of with no results. Yesterday an escrow analysis was posted to our account and states our monthly payment is going to be increased more than {$400.00} per month beginning XX/XX/XXXX ( due to their error ). 
They fully admit they made a mistake - we were told the other client 's name was vaguely similar and had an account with them - but does not pay insurance out of escrow - so they are sorry but they have to get money from them. 
I have spent hours on the phone since XX/XX/XXXX and keep being told they are investigating the error - but have not credited our escrow which now is in a negative balance. I feel our escrow money has been fraudulently compromised and needs to be replaced immediately.
