I hope this gets sorted out for you sooner rather than later. I know first hand how stressful this type of thing can be. I got a similar amount of money stuck on Crypto Dot Com and, although, as you say, not a huge amount to some if was a sigificant amount to me.
I don't know anything about ionomy but hopefully this will just turn out to be a bit of a blip and you'll get your money back soon.
Sorry you suffered a loss as well. I would steer clear of Ionomy as more people have come forward having problems with them too.
