Amerisave Mortgage Complaint

Amerisave Mortgage department,

Conventional fixed mortgage Loan servicing, payments, escrow account California

My loan is being serviced by Amerisave. In addition to my regular monthly payment, I have been sending $2000.00 in additional curtailment every month. Each month, Amerisave records the amount as $120.00. Each month, I contact them to request it be corrected. The corrections are resulting in wildly erroneous calculations and my outstanding balance is not being calculated correctly.
