TD Auto Finance Holding my refund for 20 days are more, charge me interest but refusing to pay me interest while waiting on my refund Lewiston Maine

I traded my 2014 Rav4 financed by TD Auto--my car was paid off on 4/8/2016 it has been over 2 weeks no refund on my loan payment that was drafted out of my account, so I inquired would they pay me interest on holding my money because I lost a difference of 23 because they waited for there pay off. after waiting 30 minutes on phone for a manager to assist me the rep return to line and said the higher up team was not available but she was informed no compensation for my lost in cash and I would have to wait 20 to 30 days and it did not concern her the least when I told her how unfair that was and I would call BBB. I feel if they would cost me a 23 dollar lost because of daily interest but no compensation for my long wait. I think this is a rip off to the consumer he is charged fines if they are late on payment and charged daily interest.
