I made a withdrawal request on saturday and got it processed on monday in due time (within 1 business day). So far nothing to complain about. I have put 1.5k with them a couple of months ago and so far got 1.3k out and 500 "reinvested" so pretty close to breakeven.
Losing $700 or 45% of your original investment is close to breaking even?
$500 lost from reinvesting + $200 from original investment minus payments = $700 lost.
You computation assumes the payments have stopped. He might have $700 yet to go, but that doesn't mean it is "lost".
However I also don't think you read it correctly. Sounds like he now has $2k invested and has keep $800 back. So he has $1200 to go until he breaks even. Probably before that the $1.5k will be complete and he should get that back in about 60 days.
