Citibank Mortgage Complaint

Citibank Mortgage department,

Other mortgage Loan servicing, payments, escrow account California

for several years i have been making weekly payments on my mortgage to citi mortgage. most months these payments exceed twice the required mortgage payment. after reviewing my statements, it appears not only does the lender charge me late fees even though i have never been late,, but does not apply my weekly payments properly or in a timely fashion. i have seen my payments held for weeks un-applied, causing me to pay more in interest ever month. after spending 3 hours over 2 days trying to resolve a late fee, i am giving up talking to the - customer service people and filing a complaint. there is - - late fee and an unknown amount of interest that i have over paid due back to me.
