Dukascopy Trading Platform review: Unclosed my account

How are you dear, I have completed four courses related to on-line work in dukascopy, when I deposited 100 dollars for the fifth course, my internet was running slow during the course, so by mistake my hand was on buy instead of sellthey have closed my account, now they are saying that I should do a supplementary course, but I don't have 250 dollars, which I deposited earlier was also borrowed. The tutor does not answer anythingplease restore my account so that I can get my loan back
