If I understand it correct, amazingrando only paid 85% of its Investors.
Thats probably the reason I did not recieved any outstanding dividends

In that case: SCAMMER TAG the bastard!
No, it's worse: he says that he (over)paid a small group of his investors who own 85% of the bonds.
Problem is that he OVERpaid them, since the dividend payments should be equal for all on a per bond basis, and he paid nothing to the other bond owners.
