All of those links provided on how bad they are should have been seen by OP before if he did researched about them beforehand the transaction on this platform. However, I am not blaming him because when things go bad, that's the time when we try to search for the feedback of such platforms. It's either they're telling the truth about AML reason or they're just reasoning it out to discourage you for the exchange because it is taking time. Yet, I wish that this case will be solved OP and hopefully this thread gets their attention.
I assume that OP isn't worried or OP's instinct didn't have anything that tells that changenow is a fishy website but in a way, it's kind of weird that OP knows about this forum and didn't even care to check here in hopes that there's no problems on that service, I guess to some degree, OP should know better the next time to ask questions first if they're unsure about something online that involves money. That kind of habit will definitely save OP from potential headaches, hopefully others would take note and never do what OP did so the cycle at the least isn't vicious if won't be stopping anytime soon.
