@all:
Every one here is claimed that they're scammers but seems that is not the truth.
Cause Scammers would not give the Funds back.
I see your logic but
they gave the money back after a massive online pressure. OP had to spend his own time & money (on adverts here) to create the pressure. Also this wasn't the first time ChangeNow decided to keep the money because "the client gave us a fake copy of their ID". NON of the exchanges out there hires an expert to check the ID's, they just roughly compare the selfie to the ID photo. If they don't like what they see, they can ask for another ID or release the money back to the client in a timely matter.
If this takes more than a couple of days, especially if the company cut all their communication, there's something wrong. It took this company to send the money back to the client quite a few days -
almost three months.
So yeah, they are selective scammers.
