Made a deposit which had never been credited, no response from support, finally they blocked my IP.....what do you call this? for me this is a traditional scam! avoid if you know what is good for you.
This exchange is based in Japan and I may think that they never accept traders coming from the other country which maybe you're not from Japan and so your IP address...this might be the reason why you are blocked.
I've tried to read their reviews
https://www.forexbrokerz.com/brokers/neraex-review. They don't have any negative feedbacks and so I never feel that this is a scam site.
