thanks, i just sent ~$60 to exchange for ethereum, but after 8 minutes decided to read reviews, good i found you and i could arrest the transmission in time!
I've used changer.com multiple times in the past and never had I had any issues with them. Most people that have issues with them has most likely already gotten it resolved after a few days/weeks at most. However, I can't really say for sure for currently since I haven't used them in months.
What I can say is that their rates are pretty similar to shapeshift's with crypto transactions, and after shapeshift cut down on their transaction fees, it's probably just smarter to use shapeshift for crypto to crypto exchanges.
I would still trust them with amounts under $500, for any fiat payment processors (advcash, etc.). There isn't enough evidence to suggest that they are scam at all. Complaints are quite normal, as long as they do get resolved in the end. You can actually complain about any issue and usually, the admin of the site will resolve it quickly here:
