Worst experience!!!

Worst experience ever, when you pay them lumpsum in addition to their recurring installment, the balance goes higher from the balance statement they send you monthly, same problem when you ask for settlement quotation they quote you a huge amount,and when you ask comparing to the monthly statement they send you, they will send you a complete different balance statement!! I hope I don't get to do business with them ever again. I am really not happy. Even when you send an email for a settlement quote be prepared to wait over 48hours for response during business day! I hope I am the only one who has experienced this treatment with them!
