there is usually a time limit in which erroneous trades can be reversed and I doubt its 5 or 6 months
That may be the sticking point with them, once a trade settles,it should settle. It has gone through the clearing house and all parties have been compensated..(the buyer and the seller)
Not sure if there is any way of contacting the DTC and asking that question, they hide behind a veil away from public view.
This is scary chit, might as well start your own bit coin exchange.... you too can own a house in the Bahamas !!!!
