HSBC Mortgage Complaint

HSBC Mortgage department,

Home equity loan or line of credit Loan servicing, payments, escrow account California

I have a home equity loan with HSBC Mortgage Service Center - -/-/- - - -, - : - -, Mt -, NJ - ). On -/-/-, 2013, I made a - check payment of $6000.00 towards my loan. According to HSBC 's payment policy indicated on their payment coupon, any amount above the monthly payment will be applied to the principle, but HSBC wrongfully apply the extra amount to - times of interest and principle. I called them on this mistake, they admit this mistake, but intend to confuse me with mistaken calculations. This practice is absolutely not acceptable! The amount they should deduct from my account 's principle is $1300.00. Please instruct them to correct this mistake ASAP. Thanks!
