Modification and Refinancing

i know that we have fallen in our mortgage payments in the past due to unemployment. For the past 2 years we have been on time and even have a direct debit to our account for the monthly mortgage payment.  I have or my husband has requested for a loan modification in the past and we have always been denied. I have tried other banks for refinancing but since our mortgage is not owned by FREDDY MAC or FNMA we can't get away with the high interest rate that HSBC has on our loan and at the same time our credit score is now between 650-690. Why are they not offering refinancing for current customers. They(HSBC) are making a lot of money from the customers like us who has fallen behind their payment and now they won't even offer some HELP.
