Congratulations on getting your money back. But yes, they are scamming, it is called selective scamming. You are not the first user to get their money back from this exchange, there are a few users who have also successfully gotten their money back after a long time of waiting and putting pressure on them.

There are so many scam accusations against this platform, so paying a few users does not suddenly clear their reputation. There are so many users who have their money stuck, and some of them even give up chasing it. No legitimate service operates in the way N.Exchange does.
