Very bad investment oportunity

I invested 1BTC and Bitbond congratulated me, that I am on the best 10% portfolios. Now, not even half a year later, I can be happy if I see half of my money again. I invested in loans rated D to A. Most of my Investments are made in A,B and C loans. But it looks like that half of the loans are not going to be paid back. And the promised debt-collection, is not making any progress(or is not gonna happen) since month.
