BMO Harris Mortgage Complaint

BMO Harris Mortgage department,

Conventional fixed mortgage Loan servicing, payments, escrow account Illinois

I believe my lender BMO Harris has incorrectly added excessive reserves to my escrow account and refuses to refund the excess stating the formula used to determine how much they can maintain over and above the amount required to pay property taxes is correct. I have contacted the their escrow department regarding this and they stated they are correct and within regulations, I however disagree.
