Specialized Loan Servicing LLC Mortgage Complaint

I have been slightly overpaying on my SLS mortgage ( just a few dollars a month ) since it was sold from - to SLS. For quite sometime SLS could not give me access to my account online ( I filed an official complaint with them last month, to which they finally " fixed it '' ). But now when I can see my transaction history, instead of crediting my " extra principal '' to pay down my loan, they have been allocating these extra payments to " late fee '' - not at all reducing my principal. I am sending them a complaint as well, but they are horribly non-responsive and I believe this could be a systemic issue given it appears to be done automatically all the time.
