XXXX mortgage - I have paid on time over XXXX payments, never missed a payment, and about 2-3 years ago the payments were not being applied to principle correctly. Last year nearly XXXX % of the payments were interest only. Mis-allocations continue to be made and I have to complain very month for them to adjust and re-apply. I do not believe the principle owed is correct. I have paid over {$60000.00} ( XXXX payment at {$600.00} each ) and my principle has gone from {$76000.00} ( original loan amount ) to {$69000.00} after 7 years. Every customer service representative and every escalation ends up with people saying how messed it is and how they have no idea on how to correct it, project teams were assigned to correct it and no access to them or resolution - it continues to happen.
