I am glad that you got your funds back, but I still wonder why they still had to take this long though to help you. It's their fault that they don't display warnings on the swap page, and it looks like they haven't corrected the mistake.
They're unprofessional we've been warned about swapzone & changelly. They aren't serious about their rep or else they would've corrected the mistake.
they will most likely keep (steal) the coins if you do not contact the support team and try by all means to recover your money.
I guess that's their mod of operation. Hadn't OP made a lot of noise, maybe they wouldn't have refunded the money.
Why did they return the money is it because he's complained to the forum ?
