I didn't like this from the beginning, just because of the way of communication and a lot of illogic behind them. for some reason, posts with a negative connotation in their ANN are no longer deleted as if they gave up on that and that's why it sounds like an exit scam to me.
I feel the same way, that is why I can sometimes sound harsh to new crypto business that appears in forum, it's my basic test or litmus paper for scams.They really tried to cover their tracks with creating and locking bunch of topics, arguing with me and other members, and in the end they offered me again free cards in PM.
Few members took those fee cards and they defended them, so I find them partially responsible for potential scam.
Not trying to defend them or anything, but I want to write about my experience with this issue.
Not trying so hard, but you are (again) defending them 
API problem does not explain why there is NO support, why that page is missing from their website, why there is no reply on telegram and in bitcointalk forum....
The customer support pages were always unresponsive the whole time - I only got answers via forum PM.
This is not true.I personally asked them several questions with support on their website, and now their whole support page is down
YOu should be really careful next time when you accept shady offers like this in public, especially since you are in DT1 if that crap is relevant at all
