Nationstar Mortgage Mortgage Complaint

Nationstar Mortgage Mortgage department,

FHA mortgage Loan servicing, payments, escrow account Ohio

we refinanced our mortgage last year when rates were lower and we had nationstar, they gave us to - who said they are the parent company. - told us how much our payment would be a month which was $660.00 and we wanted the lower payment from our $720.00 range so we decided to do it. At that time we owed $76000.00 and after the refinance it went up to $78000.00, the problem now is we get a letter telling us not enough was estimated for the escrow and now we have to pay the extra $64.00 a month. Now we are paying the same as before if not more because someones mistake, not on our part.And after it was refinanced they sold us back to Nationstar I have called to talk to someone and they gave me the specialist who could not answer my question as to how someone only estimated half our yearly taxes into the refinance when we have 5 years history showing what it was, I feel like it was done on purpose and they knew what they were doing and took our $2000.00 we paid to refinance also, something does n't add up here at all, why are we paying 3.5 % and its the same as the 5 % thanks - -
