I paid the full tuition amount threw my loan ($30,000)

Once i left my school, i was to be refunded $18,000

Its been 11 months since i left school, and they still have not refunded my tuition back to my bank. I should be accuring interest on $12,000, not $30,000 over the last 11 months....

are you saying the school is not responsible for the difference of interest on that large of a number?
